I am a descendant of Louis Kingsbury (b. 1821 in Quebec, d. 1897 in Belgrade, Maine). I have been unable to determine his ancestry, and several relatives tell me that it is because Louis's father used a different surname.

I recently made contact with a descendant of Louis, who says:

According to my grandmother, the original name was KINGS. An ancestor of Lewis (possibly his mother?) was the daughter of the Royal Chancellor to England in the colony of Maine. The daughter fell in love with a frenchman by the name of SRFREMROIS [I'm assuming that this is misspelled since I can't find any record of such a name]. The father / Chancellor asked his son-in-law to take the name KINGS. The name was later changed to Kingsbury.

This sounds pretty far-fetched to me... Is anyone aware of a chancellor in colonial Maine who had the surname KINGS...?
