A place to start is for you to find a date for your Rebecca!
My gg grandmother was Rebecca Aynes dau of Reuben Aynes,b abt 1805. She married Amos Lawson. Then there is Rebecca Aynes b 15 May 1828 and she married Jesse Hall. The next one is Rebecca Aynes b 1858 to Drury Aynes and Nancy R. Next is Rebecca J. Aynes b 1850 to Reuben Aynes and Bathsheba Hall. One more is Rebecca J. Aynes b to Gabriel and Clarina. I am prety sure that John Aynes and Sarah Honeycutt had a Mary Rebecca also. Mary Gardner
