I don't know anything about Clarissa's parents or siblings. Maybe the information I do have will provide some clues as to where to look (birthplace and church - see below).
I would be very interested in anything you are willing to share re: the Bartleson line, and I'll return the favor. Please email irictreas @ yahoo . com (without the spaces around the '@' and the '.', of course).
Clarissa was born January 20, 1808 in Bartonville [or Bartonsville], Northampton Co., PA, and died on her birthday, January 20, 1884.
She was a "consistent" member of the Methodist Episcopal Church [Dreher?]. She and her husband (Bartle) are buried in Pine Grove cemetery.
