Which Obadiah served 1812 and had wife Elizabeth?

According to the index at Fold3, an Obadiah Hooper served in 1812 under "GA Mil, Capt Landridge, Col Samuel Grove" [the actual captain was Sandridge - the handwritten capital S misread as an L]. The warrant was #55-80-44607.

From records at the Georgia archives, I know there was an "O. Hooper" who served "Capt. Sandridge's Co, Rifle Batt" in the Georgia Militia and was "wounded seriously" on Jan 27, 1814. This O. Hooper probably is identical with the guy whose military service led to the warrant.

And I know there was a also a Matthew B. Hooper, War 1812, who applied for a pension, based on service in Captain Garrett L. Sandridge's Company of Georgia Militia. I haven't seen the application, so am not sure which of the Matthew B. Hoopers this was, but certainly it would seem there were Hoopers in this same company who were relatives.

Then over at the BLM Government Land Office site http://www.glorecords.blm.govhttp://www.glorecords.blm.gov I see that there was a warrant actually issued to
"Elizabeth Thomas, former widow of Obadiah Hooper,"
and she transferred this warrant to Louis Megede and he redeemed it with a land patent issued in 1858. This patent was cancelled in 1859for conflicting with other patents, so Megede apparently sold the warrant then to someone else who finally redeemed it for land in 1869.

What I cannot do is place this Obadiah Hooper, who served Georgia in 1814, had a wife named Elizabeth, a woman who had been widowed and remarried but was still alive in 1855. Can someone help me figure out his parentage?
