Oh Yes, I have two HIRAM ALLENS. One is Hiram Allen born about 1796 SC died in Talladega Co. Al. after 1880.Hiram married Carna Eiland and they had a son named Isom/Isham Allen b. abt 1821 who married Martha Waford/Wofford who had a son named HIRAM T. ALLEN b. Oct 1849.
Hiram (1796) had six sons from his first marriage, I only have Isom's name, don't know the other sons names as of yet.They were all born in Jackson Co. GA as far as I know.Isom may have been born in SC as some of his descendants have him born there.But I believe that he may have been born in GA, as his parents were married in Baldwin Co. Ga in 1820.
All together Hiram (1796) had 9 children from his first marriage and8 from his second marriage, to Cynthia Waford/Wofford (Cooley). I have the names of the children from second marriage but only two of names of children from first marriage.
I would say, if your Hiram Allen's family came out of Jackson or Banks Co. GA, there is a good possibility that they are connected to my Hiram Allen (1796)
Now to the Native American part.If the Waford/Woffords women are indeed Wofford's there is a good possibility that they are of Native American Ancestry as the Wofford men did seem to marry into the NA.I also descend from Wofford's on my Ford side of the family.I do believe that these women were Woffords as they were all over the place in that part of GA during this time period, and I haven't found any Wafords in the area.
