Nathan Powell of Lee Co., GA 1840-50 did not marry Margaret Gamble.
The Coweta Co, GA marriage record shows that a Nathaniel Powell married a female w/ only the initials of M.G. on 28 Dec 1832. This was not the Nathan Powell of Lee Co., GA. There was no Margaret Gamble in Coweta Co., GA.
However, take a look at Leon County, FL marriage records: Nathan Powell mar. Margaret Gamble 12/26/1831, Marriage Book WX, page 22.
The 1830 US Census of Leon Co., FL shows this Nathan Powell. The 1830 US Census of Jefferson Co., FL (county next to Leon Co.) shows Jeremiah Powell. Jeremiah Powell mar. Violet Gamble, widow of John L. Gamble of Twiggs Co., GA and Jefferson Co., FL. Both Jeremiah and Nathan Powell show on various records in Twiggs Co., GA in the mid-1820's.
As the census records above demonstrate, they had left Twiggs Co., GA and lived in Jefferson/Leon Co., FL before the 1830 census. By 1834, Nathan Powell was a J.P. in Leon Co., FL. On 20 Oct 1835, Nathan Powell received a land grant in Leon Co., FL.
By 1840, both Jeremiah and Nathan Powell are both dead. Jeremiah Powell's widow, Violet, shows in the 1840 Leon Co., FL census.
From the Powell Family File at the Florida State Archives in Tallahassee, FL: "Jeremiah Powell came to Florida from Twiggs Co. GA about 1824. He first lived in Jefferson Co., FL and bought land in Leon Co., FL in 1830. His Last Will and Testament dated January 23, 1838 shows his wife was Violet, daughters names were Julia, Elizabeth M., and Caroline. His sons were Charles L., Adin and Joseph Powell. He died leaving an estate that included over 1700 acres and 44 slaves. Jeremiah Powell had removed to Tampa, FL shortly before his death on 24 Oct 1838. Violet Powell was the widow of John L. Gamble of Twiggs Co., GA. In Dec 1831, Margaret Gamble, daughter of John L. and Violet Gamble, married Nathan Powell, the only brother of Jeremiah Powell. Expenses of the estate of Jeremiah Powell shows the executor visited LaGrange, GA and Cahawba, AL."
From The Powell Family of Virginia and the South (Lucas), p. 40: "54c. Jesse Powell married Lydia and died 1777 in Johnston Co., NC, leaving sons Jeremiah and Nathan Powell."
Jeremiah Powell's obit from x23 Nov 1839, The Floridian (Leon Co., FL): "Died on the 24th of October last at Tampa Bay, East Florida, Jeremiah Powell, Esquire, of this county (Leon). The deceased was a native of North Carolina, but removed many years since to Georgia and soon thereafter the cession of this Territory to the United States, settled here. He was for many years before his death a class leader and one of the stewards of the Methodist Episcopal Church and by a life of unaffected piety, acquired the respect and esteem of his neighbors and associates. Having been for some time afflicted with a pulmonary affection, he was advised by his physician to go further south. In 1838, he visited South Florida and Cuba with the same object. While there, he took a violent and sudden cold which caused his death in a few days after its attack."
The Nathan Powell of 1840/50 Lee Co., GA is likely the same Nathaniel Powell of 1810 Robeson Co., NC, living close to other Powells, i.e., Douglas and Nicholas Powell. He married Charity Bird, the daughter of Rev. Isaac Bird, who died in Robeson Co., NC. She was named in his LWT in Robeson Co. NC. Nathan Powell's sister, Loramy Powell, mar. Joel Bird, sister of Charity Bird.
Another near neighbor in 1810 Robeson Co., NC was Levi Barfield. He shows as a neighbor in Robeson Co., NC and in Lee Co., GA.
Two men who are thought to be sons of Nathan Powell are living next to him in 1840 Lee Co., GA: Quinny Powell and Loami Powell. Immediately next to them is Levi Barfield, mentioned above.
Quinny Powell of Lee Co., GA moved to Monroe Co. AL by 1850 where many other Robeson Co., NC families removed to. Note there were two different Quinny Powells in early GA records. The one in Houston Co., GA and other counties was a different man.
Loami Powell of 1840 Lee Co., GA apparently died before 1850. His children show in poor school records in 1845 (Poor School Records, Folder 55, Image 2,at GA Archives.)
Quinny and Loami Powell drew a total of 4 lots in the 1832 Cherokee and Gold Lotteries. Two lots fell into Paulding Co., one lot in Cobb Co. and the Gold lot drawn by Loami Powell (Lot 85, 24th Dist, 2nd Sec.) was on the county line between Gordon Co. and Gilmer Co.
Thomas Powell b. 1839-40, shows in the household of Quinny Powell in 1850-60 Monroe Co., AL. It is not known if this is a son of Quinny or Loami Powell. Rev. Thomas Wm Powell moved back to GA between 1860 - 62, served in Co. I, 63rd Georgia Vol Infantry Regiment, and became a Bapt. preacher. He died Berrien Co., GA in 1887.
