In the 1860 census, William BUTTERFIELD (b. 1836/1837, possibly in Somerset County, ME) is living in Jackson Brook Plantation, Washington County. His wife is named Martha - I believe her maiden name was MILTON. She was born in Nova Scotia, Canada, in 1837. At that time they had 2 boys: Frederick, b. 1855, and Herbert, b. 1860; both boys were born in Maine.
They moved from Maine to Minnesota about 1866/1867, and from there to California some time between 1873-1880.
I'm looking for information on their time in Maine: the date/place of their marriage, birth dates/places for the boys, and anything else that might be helpful.
