Your query fascinates me. We have looked for a William Allen for several years that would be a brother to John M. Allen who was b in Prince George's Co, MD 1794/95 - md Mary W. Blundell b 1797 Fairfax Co, VA .They had a dau Emily b 1823 VA that md Shepherd Brown Philpot b 1819 OH on Dec 31, 1816. Also for years, a William Allen's descendants - he ties into Mary W. Blundell's father Daniel who married a 'widow' Allen abt 1795, having Mary, William Colvin, and an Anna before she died.Daniel William Blundell's second wife was Mary Francess/Francis, and they had 6 more children, five b VA.The oldest of these, John Alexander b 1817 OH md Sarah Ellen Allen b 1827 Alexandria, DC, now VA, dau of Dennis Allen b 1794-1799 Alexandria, and Charity Payne b 1806 Alexandria.
We've been told that Dennis had a brother James, and their father was a William b abt 1782 or earlier. Washington, DCLiber WB 118 - 1845 William Allen deed to John A. Blundon - 488 Old Record 413 New Record - this could have been Dennis's father conveying this deed. To add to this confusing saga, John Alexander's last child born Feb/Mar 1861 was named Carrie Heath Blundon.
The Blundells and Blundons, within the same family, called themselves whichever they preferred.This is all one family that started out being Blundel/Blundall/Blundell and has evolved to also include Blundon/Blunden/Blandon/Blundin.
I realize this is a lot for you to digest.
Would you have a more complete breakdown for William B. Allen and Emily Heath, such as dates, who their children are, etc.
I see by the 1860 census that they also had Laralie? 19, James N or W 14, in addition to Epenetus.I looked at the 1870 and found 4 different James Allens that could be their son.But which one?
Perhaps by our working together, we might find some answers?
