Indexes and transcripts of documents provide clues about our ancestors’ lives. However, they typically do not show all information found on the original document. Sometimes, I am so excited to find any information about an ancestor that I forget about a basic principle– indexes and transcripts are just the beginning. The original document tells more of the story. In this post, I tell about a marriage record, a death record, and implications for my future research.

For the past several months, I have been writing a manuscript about my mother’s German ancestors who immigrated to America. I already have copies of some original documents. As I wrote, I identified and requested copies of other documents. New York City Archives staff usually respond to my requests within a few weeks. Documents from New York state continue to trickle in. One marriage record, the subject of this post, especially confounds me.
A short family history. Valentine Maurer, my mother’s great grandfather, immigrated to the United States about 1855. His death certificate[1], received in 2015, listed his parents as Leonhard Maurer and Marie Maurer, both born in Baden, Germany. Additional research revealed that her maiden name was Metzger (details for another post). So far, so good. I searched for more information about Leonhard and Marie, eventually finding them in New York City in 1865. [2]
Next item found, by chance, was a Manhattan, New York marriage index entry for 70-year-old Leonhard Maurer and Crescentia Ley/ Leu. [3] Leonhard’s age corresponded to other records. In August 2021, I found a similar marriage record index entry on a different online database.[4] This one had a certificate number so I requested a copy of the marriage record and received it on 29 August 2021. [5]

Name: Leonhard Maurer Event Type: Marriage Event Date: 15 Aug 1870 Event Place: Manhattan, New York, New York, United States Event Place (Original): Manhattan, New York Sex: Male Age: 70 Marital Status: Unknown Race: White Birth Year (Estimated): 1800 Birthplace: Baden, Germany Father’s Name: J… Maurer Mother’s Name: Theresa Metzgas Spouse’s Name: Crescendia Leu Spouse’s Sex: Female Spouse’s Age: 51 Spouse’s Marital Status: Single Spouse’s Race: White Spouse’s Birth Year (Estimated): 1819 Spouse’s Birthplace: Baden, Germany Spouse’s Father’s Name: Peder Leu Spouse’s Mother’s Name: Sabina Heusler | Name: Crescentia Ley Gender: Female Marriage Date: 15 Aug 1870 Marriage Place: Manhattan, New York, USA Spouse: Leonhard Maurer Certificate Number: 4936 |
The Family Search entry seems fairly complete. What more could be on the original document? Well, there were several items of interest. Specifically, the certificate included Leonhard’s occupation (saloon keeper), “number of husband’s marriage: No. 3” and “no. of wife’s marriage: no. 1.” Leonhard had been married two other times! I know of only one- Maria Metzger, Valentine’s mother.
Based on the 1865 census and 1870 marriage, Maria probably died between 1865 and 1870. At about the same time as finding the 2nd marriage index entry, I found a death index entry for Maria Anna Mearer, age 63, who died in 1867.[6] Close enough to spend $15.00 for original certificate! I received a copy of that certificate on 2 September 2021.[7] Names of her parents are not recorded. How do I know that she is MY Maria Maurer? Her age of 63 is somewhat consistent with Maria Maurer, age 62 per June 1865 census. Address of Schols street, 16th ward is roughly consistent with the family’s location in 1865. “Resident of this city: 10 years” is consistent with 1857 immigration record for Leonhard, Maria, and three of their daughters.[8] In addition, a November 1823 marriage record for Leonhard Maurer & Maria Anna Metzger indicates that Maria was born in 1804.[9] I can now say that she is probably the same Maria Maurer living with Leonhard in 1865.
Per June 1865 census, Maria reported 14 children.[10] I found records for 13 children born 1825 to 1852. My first list included two children, born January 1821 and October 1822. I initially dismissed them as being born outside of marriage. Now, I must consider that these two may have been born to Leonhard and his 1st wife, possibly also named Maria. And, there is one more child to be found for Leonhard and his presumed 2nd wife, Maria Metzger.
In summary, based on currently available information, assertions are:
- Leonhard Maurer & 1st wife: 2 children, born 1821 & 1822;
- Leonhard Maurer & 2nd wife, Maria Anna Metzger (1804-1867), married 1823; 14 children born 1825 to 1852; 13 children identified so far; and
- Leonhard Maurer & 3rd wife, Crescentia Leu, married 1870, no children.

REFELECTION
Don’t underestimate the importance of research logs. Include even questionable information and why you question it. Track everything, even indexes/ transcriptions. Record the date you order and receive certificates. Original certificates will likely have information that is not on index. Transcriptions also may not include all information that is on the original document.
What I learned (again!): New information, beyond what is indexed or transcribed, is usually on an original document. A complete research log takes some time now but will save time later. Search more than one database. If information is not found, check back in a few months. Be sensitive to alternate spelling of names.
What helped: Fairly complete citations from previous work.
What didn’t help: I didn’t have digital/ paper copies of all indexes/ transcriptions.
To-do: Review German records again. Ask my German friend if he is willing to translate. Continue systematic ordering of original BMD certificates.
