Via DNA match Ada came up as Adelaide Ackerman married to William Bernard Cooper who died in 1897. I don’t believe Ada ever went by Adelaide. However she did go by Addie.
In the 1870 Census we have Ada N Akerman age 0 or 1 with a 17 year old Sarah Stephens both living in the Shrider household. Possibly Sarah’s grandparents.
Also in the 1870 census we find Albert living with William and Kezia. Albert is 17 at the time of the census.
Then in the 1880 census we find Adda age 12. This was a little confusing as they listed Adda as granddaughter. Usually related to Head of Household. Of course listing A. Akerman as Head of Household obviously isn’t the grandparent of Adda. So they listed her as granddaughter of Kezziah.
I believe A. is Albert. Albert was born in 1852 and would have been 17 or 18 in 1870. Also Sarah Stephens was 17 at the time of the 1870 census.
So it’s my belief that Sarah is Ada’s mother and Albert is Ada’s father. Ada being very young in 1870 was still with her mother then at some point went to live with father Albert.
According to the DNA match Ada or Adelaide was married to William Bernard Cooper from Nebraska. In the 1900 Census lists William and Addis (but could be Addie) were living in Crawford Nebraska.
As you notice her age is not listed.
In the 1910 Census we still find Addie and WM living in Crawford Nebraska.
In the 1920 Census it shows Widow Addie living with her son Lysle Winston Cooper therefore William Cooper died after 1910 but before 1920. Then moved to Colorado with her son.
The next Census I have is from 1940 Maryland which shows Lyle (Lysle) and family including Addie.
As you see Addie and son Lysle traveled a bit after William died. We know that Addie passed away in the 1940s as she is not listed in the 1950 Census.
