My 3x great-grandparents John Chilcutt and Catherine Harmon were living in Caroline County, MD in 1850. Their last name was spelled Chilcote and John's occupation was given as Carpenter in the census record.
In the 1860 census, the family is in Talbot County, MD. This time John's name is recorded as John W. Chilcutt and his occupation is given as Farmer.
George is my 2x great-grandfather.
I didn't find any definite entries for the family in the 1870 census, but there were some Chilcutts with some of the children's names living with other families. It's possible that John and/or Catherine died by 1870 and the family was split up. George was married to Kate Covey by the time of the 1880 census, but I didn't find him in 1870. I'll post an update when I find out what happened to the family after 1860.
