The more you look at records the more that you will find that the spelling of names can change dramatically. Prior to the 20th century many folks could not read or write. Presumably, the Census enumerator and the Town Clerk could read and write but used a phonetic spelling because the individual being enumerated could not spell or make a correction.
The native language of the enumerator and the individual being enumerated were often different. In Maine, an enumerator transplanted from Massachusetts would have a difficult time spelling the name of a French Canadian or a Swede living in Caribou. You can imagine the enumerator trying to spell Håkan Nilsson or François Pelitier as he went from a Swedish household to a French household.
The Civil War was brutal for Maine. Of my father’s four great grandfathers, three died in the war. Beginning with the 1870 Census one will find many blended families. The work-around is to look for the individual children, by their first name, that were enumerated in the 1860 Census. The last name of the children in the blended family could depend on the age of the children when the father died.
The Rackliffe connection is via my grandfather's sister,Dorothy Louise Hendrix Driscoll (born 1895, died 1993). Aunt Dorothy lived in Augusta from about 1919 until her death. Her daughter married Russell Forest Rackliffe (born 1918, died 1998)in 1947. I’ve traced his family back to Oliver Rackliffe (born about 1831). Up to the 1920s the family lived in Rockland, Knox County.
