Hi, I have a handwritten record of Asa by his sister, Clarissa Ann Hewen LaFrance that states that their parents were Asa Hewen, Apr 8 1785 and Rachel Sturdevant Aug 14, 1789. They were married on june 8, 1809 and I have dates/names of 11 children. The 1880 census says Asa born in CT and Rachel in PA. you may contact me at
shauntelleanderson@q.com if you want copies. I would love to know what you have on Asa Jr as well!
