Charles Dahmer married Anna E.Ward - the daug of Ann Eliza McDermott Ward - Ann Eliza was sister to my gggm - Francis McDermott.
Anna Ward was the only one of the 6 children of John and Ann Eliza to survive to adulthood.

I got all my info on them from a bible record I found at Rutgers Library.
I haven't gotten any of the Dahmer birth/marriage/death records.
Just sort of stopped after I got the bible.

Here they are in the 1880 census
1880Census Place: New Brunswick, Middlesex, New Jersey
