I am finding all this Abston orgin to be very interesting. However, I'd like to add that from the info I was given that I am trying to verify, I have the family tree listed like this: Elijah Abston b1800 to Elijah Abston b1770/d1846 and Nancy Prewitt. The elder Elijah being the son of John Abston b1731/d1788, son of Francis Abston b1700/d1762 and Susanna Ball b1704/d1762. Francis being the son of Samuel Abston b1690/d1790 (although I'm sure that's a mistake), who is the son of William Abston b1655/d1737 and Mary Moy b1665/d1745. William being the son of another William b1625/d1681 and Elizabeth Gilbert or Smith b1630 in England.
I'd love to find more information or verification on any of this!
