Individual Details

1870 census lists his age as 60 and 1880 census lists his age as 69 which would indicate a birthdate of about 1910.
The 1870 census indicates that both of his parents were foreign born.

Their oldest child, Elizabeth, "Lizzie" ws born in 1850.

Death

He is listed in the 1870 census as living in Madison Twp, Montgomery Co OH with his wife Margaret and five daughters. His age is 60 and the record indicates that he and both of his parents were "foreign-born."
In the 1880 census he (69 years old), his wife Margaret (63 years old) and their youngest daughter, Viola (12 years old) appear to be living in the household of their daughter Elizabeth (31 years old) and her husband John T. Helstern (34 years old) and their three children George (8 yo), Cora Mae (6 yo) and Margaret (4 yo) in Madison Twp, Montg Co OH.
The name "Dulaut/Dulot/Dolartz" does not appear in the 1900 census of that area.
