Several users and curators are interested in the Pratt families. There were multiple Pratt families and they have been confused.
One Pratt family was in Weymouth and for them I found a decent source: https://mattocks2.wordpress.com/2008/05/10/genealogies-of-the-early...
Joseph Pratt, of Weymouth had a son John Pratt, of Weymouth who was born 17 May, 1668. He was NOT the husband of Ruth Stimson.
Thomas Pratt, of Watertown had a son John Pratt, of Watertown, birth date unknown circa 1668 also, who WAS the husband of Ruth Stimson.
John Pratt, son of Phineas Pratt of Plymouth, married Anna Barker. His son, John Pratt, of Kingston RI, married a woman named Anna. He did not marry Ruth Stimson.
The source for the last family is: http://aleph0.clarku.edu/~djoyce/gen/report/rr10/rr10_161.html#P85234
Please will the user(s) and curators interested discuss this. There was a lot of confusion among these families and I'd like to get it correct and ensure that it stays correct.
