Here is the 1900 US Census for my great great grandmother Abigail, her second husband, Wilson O. Daniels, a boarder named Leonard Hall, Abigail's mother Elizabeth and two of Abigail's children, Alice Mabel and my great grandfather, Fred Daniels.
The family was living in Chicago in a community called Lake.
The census taker must have thought Wilson's middle initial "O" was part of his last name, however, his last name was Daniels.
Wilson was employed as a foreman in a stable.
This census fails to account for Abigail's youngest son, Frank, as it only indicates Abigail had 2 children, which leads me to believe Frank passed away as an infant, probably in Washington, Iowa.
