U.S. States: New York: Otsego County
Kingman Brown b. 5/9/1791 was born to Reuben Brown and Joanna Smith.in New Marlboro,Berkshire MA.I'm not sure, but there is a good chance that the father, Reuben is from Canterbury Township, Windham CT b. 6/30/1747. There were several Joanna Smiths on familysearch.com. Many of the Browns from Windham County CT migrated west and on to Otsego, NY. My Sarah Brown was the daughter of Stephen Brown of Killingly, Windham, CT. She married Joseph Griffin,(also from Windham CT) and they moved to Otsego Co. I am also connected to an Abigail Brown from Windham, Windham Co. CT, who married a George Anderson, and had Lemuel Anderson who migrated to Hartwick, Otsego Co. I am adding the website where there are Births and marriages recorded for Windham County, CT. http://www.geocities.com/Heartland/Fields/4791/barbourcollectionvrindex.html
Good luck on sorting this one out! I think this Kingman is probably yours, though. There was only one in all of Familysearch.
