I am searching for more info for parentage [and beyond] info for Frances "Fannie" Thompson Allen b 4 Jan 1800 Clarksburg, TN; d. 19 Feb 1881 Daytonville, Iowa. She was a Quaker. Her father is reportedly Aaron Thompson who married Rachel Clark. I have source info on a 20 Jan 1794 marriage in Harrison Co. WV. Birth for Aaron 20 Mar 1760 Somerset Co., PA, d in Sullivan Co, OH. Birth for Rachel 23 Jun 1773. Other names: John Clark the father of Rachel, no mother's name. Possible parents for Aaron could be William b 1730 and Elizabeth b 1735 but I have no clear and convincing source info so I am looking for some leads or others who may be descended from Aaron and Rachel. They reportedly had about 10 children. Thanks in advance. Gayle
