Background
My ancestors all emigrated to Australia in a 35-year period between 1848 and 1883. My goal for my family history work is to confirm my ancestors genetically back to the family that they were born into prior to emigrating.
Claire Hinton researched the family of Johan Jakob Steinhauser extensively, even visiting Butzbach in Germany. Claire had been supported by a number of family members including Helen, who shared some of Claire’s earlier work with the researcher. Following the leads in this material with the help of a Steinhauser cousin living in France, allowed much of the documentation to be validated. DNA matches would be small to validate a great-great-great-grandparent in Germany, so a surname search was conducted: search for “Steinhauser” as a “surname in matches’ tree” in the researcher’s match list. This approach yielded a DNA connection for the Steinhauser family in the USA which led to Jakob Steinhauser’s nephew, Johan Wilhelm Fischer who was known as William Fischer in the US.
This research identifies the German ancestors for Jakob Steinhauser by proving the connection between the descendants of William Fischer and the descendants of Johan Jakob Steinhauser who emigrated to Australia.
Research Question
Johann Wilhelm Fischer was baptised 11 Sep 1864 in Butzbach as the son of Johann Conrad Fischer and Elizabeth Apollonie Fischer née Steinhäußer.1 Is he William Fischer who marries Catharine Hearty in New York, 21 May 1887?2
Conclusion
Johann Wilhelm Fischer (1864) was the son of Johann Conrad Fischer and Elizabeth Apollonie Fischer née Steinhäußer as per his baptismal record in Butzbach.1 He is the same William Fischer who marries Catharine Hearty in New York 21 May 1887.
The Return of Marriage2 for William Fischer and Catharine Hearty shows that William Fischer’s mother is Eliza Steinhauser and his father is Johan C Fischer aligning well with the baptism record. Letters between Christof Vogt in Butzbach and Jakob Steinhauser, Wilhelm’s maternal uncle in Australia, establishes that Elizabeth was known as Elise similar to how she is recorded in the US and that she had married Conrad Fischer.3 The only contrary evidence is the birth location being specified as only Germany in all US records, with no link to Butzbach in the US records.
Negative evidence supports this conclusion. A search for any marriage between an Eli* Steinhauser and a Fischer male in Germany between 1845 and 1865 returned no results, making it unlikely that another family with near-identical parent names existed from whom a different William Fischer could have emigrated.
The sharing of DNA between four descendants of Johann Wilhelm Fischer in the U.S.A. and five descendants of Johann Jakob Steinhauser in Australia, confirms a genetic relationship connecting the descendants of the two Steinhauser siblings – Johann Jakob in Australia and Elizabeth Appollonie in the USA.

Baptism Record
The original image of the Baptism Record for Johan Wilhelm Fischer was accessed via FamilySearch1 and transcribed using the original image1 and Transkribus. The text was then translated using Google Translate to provide the following text. Note that this text has not been independently verified by a professional German translator, but is consistent with the details supplied by both the FamilySearch transcription3 and the Ancestry index record.4 The independent transcription and translation provides additional details such as Johann Wilhelm Fischer’s birth date of 11 Aug 1864, his father’s occupation as a master tanner and that he was named after his father’s brother, who signed the baptism record.
1864.
Johann Wilhelm Fischer, 28th, in the year of Christ eighteen hundred and sixty-four, on the 11th of August in the evening around twelve o’clock, according to the credible report of Johann Conrad Fischer, local citizen and master tanner, his second child, their first son, was born to his wife Elisabeth Apollonie, née Steinhäußer, of this place. He was baptized on the 11th of September and named Johann Wilhelm.
The witness was Johann Wilhelm Fischer, unmarried brother of the child’s father, who signed this document along with the child’s father and only the baptizing priest.
Joh. Conrad Fischer.

John William Fischer’s birth year varies between 1863 and 1865 for the records (Table 1). These records were self-reported. The reported dates centre around the birth date reported in the baptism for Johan Wilhelm Fischer of 11 August 1864. The baptism record is an original source with primary information recorded at or near the event; the Marriage Return and other records in Table 1 are derivative information provided by John William Fischer years later.
His wife being Catherine from Ireland as well as various addresses in The Bronx, New York and associated cook/chef type occupations until 1925 when he is listed as a watchman, provides consistency for the records.
John William Fischer’s place of birth is given as Germany. US vital records often have only a country recorded. On the Marriage Return, William Fischer’s father’s name is recorded as Johan C Fischer and his mother’s name as Eliza Steinhauser. Eliza being used as a diminutive is consistent with the use of Elise for Elizabeth Apollonie confirmed by letters included in Claire Hinton’s self-published family history.11 The parent names are near identical to the baptism record for Johann Wilhelm Fischer.

Claire Hinton’s Research — Growing Up in the Thirties and Forties11
Claire Hinton, a descendant of Johannes Steinhauser (1808) in Australia, self-published a book about her ancestors.11 Johannes Steinhauser and wife Klara Susanna Grunninger had two children who survived childhood: Johann Jakob, known as Jakob, who emigrated to Australia in 1854 and Elisabetha Apolonia Steinhauser12 or Elise as she would be known, who was “named in honour of Johanne’s sister Elisabeth Appollonia” (p. 15).
Addendum VI13 of Claire’s book includes the translations of seven letters and how they were found in 1993 in Butzbach in an old storehouse behind “Haus Vogt” that was to be demolished. The letters were a correspondence between Jakob Steinhauser in Clunes, Australia and his uncle Christof Vogt.
The following extracts from the letters13 confirm that Jakob Steinhauser’s sister Elise married Konrad Fischer and that her name was known as Elise within the family rather than Elisabetha Apolonia Steinhauser as she was baptised.12 In addition, the letters also suggest that emigration to the US was being considered by the family prior to William Fischer’s emigration.
On the 14 Apr 1872 (p.30) “Uncle E. C. Vogt” wrote to Jakob: “You wrote to your sister and brother-in-law […] Your brother-in-law, Konrad Fischer, is very ill. […] Instead of letting him go to Australia, I would persuade him to go to San Francisco.”
On the 19 Aug 1872 (p.31) “Your loving Uncle, E. Chr. Vogt” wrote to Jakob, referring to the death of Konrad Fischer: “Your dear sister Elise has great problems with the running of the house and the farm after this sad event”.
Jakob Steinhauser wrote to his Uncle 10 Jul 1876 (p.31): “I want information about my sister Elise and her family. I have heard nothing from her for 3 years and cannot understand why. I always send her letters.”
Claire Hinton refers to Jakob’s uncle as Christof Vogt. Jacob Vogt’s 1878 marriage record14 names his parents as Ernst Christoph Vogt and Elise Apollonie née Steinhäußer, confirming both the full formal name of Christof Vogt and that his wife Elise Apollonie was born a Steinhäußer — Jakob Steinhauser’s aunt. Claire Hinton’s book notes that Jakob’s sister Elise was named in her honour (p. 15). The use of a middle name or shortened form for everyday use is consistent with naming practices seen throughout this family, including Elisabetha Apollonie being known as Elise or Eliza.
Claire Hinton’s research describes that Johannes Steinhauser (1808) had a daughter baptised Elisabeth Appollonie. She was known as Elise to the family and she married Konrad Fischer. This information matches the mother named on John William Fischer’s Marriage Return2 as Eliza Steinhauser married to Johan C Fischer. Four name variants are used for Elizabeth Apollonie, as shown in Table 2. They are consistent given time and geography differences.

Autosomal DNA Evidence
A DNA connection for the Steinhauser family was identified by searching for “Steinhauser” as a “surname in matches’ tree” in the researcher’s match list. A DNA match was identified, and their shared matches identified.15 The matches that could be placed in a tree (Appendix 1) are documented in Table 3. The documentary chains for the US testers vary in completeness, and the structure for the US family is based on their match data to each other.
An autosomal DNA cluster confirms descent from Johannes Steinhauser and his wife Klara, as per the tree in Appendix 1. Note that one tester’s parents were both descended from Jakob Steinhauser’s children and were second cousins.
At the relationship distances involved in this analysis — 4C1R and 5C1R — DNA sharing is not guaranteed. The identification of multiple consistent DNA connections between descendants of the two Steinhauser sibling lines, despite Johannes and Klara having only two surviving children with tested descendants, is therefore a meaningful finding rather than an expected outcome.
BanyanDNA is not recommended for theories that rely mostly on 4C relationships or beyond and/or matches less than 20cM. The theory tested in this research is all based on 4C relationships and beyond although match sizes are generally greater than 20cM.16 The matches therefore demonstrate a family connection rather than a specific relationship.

Negative Evidence
All of William Fischer’s records specify his birthplace as ‘Germany’. No region or town is ever identified. Because of this, negative evidence required a search across all available German marriage records. A search of Ancestry’s German marriage records 1845–1865 using ‘Eli*’ Steinhauser returned 142 entries across all German states. A review of the women with Steinhauser or variants as their surname, approximately 25 women, found that no woman married a man with the surname Fischer in the record set. FamilySearch was searched using Records (name: Steinhauser, marriage: 1845–1865, in Europe, spouse surname: Fischer) and Full Text (name: Steinhauser, marriage: 1845–1865, in Europe) searches which found no relevant records. This search may still be incomplete as Hamburg has not been searched.17, 18
Evidence Evaluation / Evaluation of Competing Hypotheses
Hypothesis 1: William Fischer on the Marriage Return is not the same person as the Johann Wilhelm Fischer baptised in Butzbach.
RejectedRejected as unlikely, based on:
- Presence of DNA matches between descendants of the Steinhauser siblings.
- The coincidence of names — Eliza Steinhauser married to a man with a surname Fischer in Germany could not be identified in the 20 years prior to 1865. Variants of Eliza / Elise / Elizabeth using the wildcard search “Eli*” Steinhauser married to a Fischer between 1845 and 1865 in Germany were used with no successful identification.
Hypothesis 2: John William Fischer was born in Butzbach to Johann Conrad Fischer and Elizabethe Apollonie Fischer.
Proven Basis of Proof:The convergence of Johan Wilhelm Fischer’s baptism record, John William Fischer’s Marriage Return, and the letters preserved through Claire Hinton’s book that describe John William Fischer’s mother’s diminutive name, Elise, and her marriage to Konrad Fischer together with DNA matches between descendants of Elise and Johann Jakob Steinhauser’s descendants is beyond reasonable doubt.
Limitations and Constraints:- Chromosome-level triangulation is unavailable due to the use of AncestryDNA.
- BanyanDNA is not recommended for theories that rely mostly on 4C relationships or beyond and/or matches less than 20cM. The theory tested in this research is all based on 4C relationships and beyond although match sizes are generally greater than 20cM.
Closing Statement
The combination of information in records and multiple DNA matches between the Australian and U.S.A. families and consistent autosomal cM values across descendant lines establishes Johann Conrad Fischer and Elizabeth Apollonie Fischer of Butzbach, Germany as the parents of Johann Wilhelm Fischer, known in the United States as John William Fischer. The limitation of chromosome-level triangulation being unavailable due to the use of AncestryDNA is noted.
