Here is the 1850 US Census for my great great great great grandparents, Olive (Jacobs) and Henry Emery. They were living in Joshua, Fulton County, Illinois with their children, David (my great great great grandfather), James, Elizabeth, John, Edith (Caroline), Sarah, William, Jason and Catherine.
Their two eldest daughters, Mary and Amelia had married and had moved away with their husbands.
This is the last US Census for my great great great grandfather as a single man. In either 1852 or 1853 he would marry my great great great grandmother, Sarah Dwire (or Dwyer).
This census was also an improvement over previous census records as it included the names of all of the members of the household, their ages as well as the state of their birth.
