Hi Dorothy, I did a little more searching tonight and this is what I found - hope it helps:
Elizabeth Allen was b. @ 1792 in Edgefield District, SC and died before 1882
her father was Benjamin Allen b. @ 1774 in VA and died before 1840 in Barnwell Distr. , SC
her mother was Jane Russell b. @ 1755 Darlington Co, SC
her mother and father had 11 children born between 1777 and 1798 (I didn't try to put them all down - you can use worldconnect to find them)All 11 kids are listed as born in Edgefield, SC
Elizabeth Allen and James Bagley (b. @ 1790) were married 4 Mar 1813 in Franklin Co, GA.
Col. Asa Allen married Ann Wood (she may have been a widow) They were married on 18 Jun 1818 in Franklin County, GA
Asa Allen is listed on the Tax list of Franklin County, Ga for the following years: 1802, 1806, 1807, 1808, 1811, and 1819 I have no explanation as to why he is not listed in consecutive years. Perhaps they have not published those years on the internet yet.
So it would seem that Elizabeth Allen was NOT BORN IN NC as some have noted.You can probably find out more about her in Edgefield Dist. of SC.
Hope this helps -This is not my Allen family - have no other info at the present.
