My theory is that Thomas Jefferson Allen was the son of Jesse Allen, and grandson of George, both of Greenville, South Carolina.I am going by recollection right now, because my records are disorganized, but: 1.George, of Greenville, South Carolina, in his will, identifies a son, Jesse. 2.There are two listings for Jesse in the 1810 Greenville, South Carolina census- because they are virtually identical, I believe them to be for the same person. The family profile for 1810 Jesse is the same as those for the following Polly and Mary. 3.By 1820, there is no listing for Jesse Allen in Greenville, but there is a new listing for Polly Allen, who has four sons and two daughters (if the children enumerated with her are her own children) 4.Polly is a nickname for Mary. 5.In 1830, widow Mary Allen is listed with the same family profile as 1820 Polly Allen. 6.In 1840, there is a "Jefferson" Allen enumerated in Greenville, as well as Mary. 7.Thomas Jefferson Allen, born 1808, had a son named Jesse Crawford Allen. 8.In 1850, Mary Allen was enumerated with H. B. Allen in Greenville.H.B. Allen was of an age to be her son.I further believe H.B. Allen to be the Hannibal B. Allen for whose estate a probate order was issued, after 1850, in Greenville. 9.Thomas Jefferson Allen has a son named Hannibal, born in 1844 in Tennessee.
So, in my view, circa 1785 Jesse Allen dies young,having had sons named Thomas Jefferson Allen and Hannibal B. Allen.He also had two other sons, and two daughters. Thomas Jefferson Allen names sons Jesse Crawford Allen and Hannibal Allen after his father and brother, respectively. [The name Crawford I believe to be the surname of Thomas Jefferson's wife]
