Looking for a connection between Michael b 9/8/1842 Germany d 9/14/1926 Queens, NY and Joseph Heinlein b 4/1869 Germany lived in Brooklyn, NY.
Michael was a sponsor at Joseph's marriage to Kunigunda Fetsch in 1891, Brooklyn, NY.
Use FS Person ID numbers for folks to look up and help.
This will likely require a deeper dive into both individuals and their families. A link may show up when you get generations properly sourced, and an extended family shows some connection Uncle & Nephew(?)
Thank you, I'll try that.
