Clifford was born on November 23, 1915 and was the son of Edson John Mills and his wife, Julia. Census records for 1930 in Franklin County, Vermont, indicate that Clifford emigrated from Canada in 1920 at the age of six. That is also the year that his parents married, so Edson must have adopted Clifford. The records state that he and his parents were aliens at the time of the census. The records also indicate a previous marriage for Clifford's mother at age 20. Whether or not Julia is his biological mother is also in question as she emigrated to Vermont much earlier than either her son or husband.
