My wifes family was/is Quaker, and has long standing Quaker roots. The Quakers are quite methodical in there record keeping, so we can get much information from them. They also were a small community, that mostly kept within itself for finding mates (marriage to someone not of the faith was grounds for the church to apply discipline).
They also use an unusual notation for dates. Since many of the Month and days of the week were name for pagan gods, they would refer to them by their number. Thus 1st Month would be January, or March if the Julian calendar was still in use.), and Sunday was refered to as 1st day.List of Quakers
