Margaretta Halford born 1900 in Massachusetts to Walter and Mary Halford.
I find her on the 1910 and 1920 census for Hartford, Connecticut. (1920 her name was misspelled as Margaret). Then on the 1930 census she is listed as Margaretta Miller, still living with Walter and Mary along with 5 children. Shirley 6, Walter 5, Norman 3 (my grandfather) Majorie 1 and Jean 0. All 5 children also have the last name Miller.
A lot can happen in 10 years! My great-grandfather is not listed here. Does anyone know his first name? Did he pass away after Jean was born? Did they get divorced? I cannot find any records.
