We have not talked for a while, and since I just ran across this posting by you, I decided that I would share a few of my thoughts and ask some questions.
Some of the descendants of Thomas Wrenn and Mary Driver have stated that Thomas' parents were James Wrenn and Mary Hamlin, and Mary Hamlin Wrenn was living with Thomas and family during the 1850 Census. The Hamlin name seems to have major consequences with the Wrenns in Person County. My Sidney Wrenn married Catherine Dicey Gregory 25 October 1828 in Person County; that marriage was provided bond by Nathaniel Hamlin/Hamblin;John Franklin Wrenn who married Frances Carver 7 January 1825 had their marriage bond provided also by Nathaniel Hamlin; William Warren Wrenn married Leatha Ann, "Leathy" Hamlin as his first wife.I have not seen a marriage bond for them, and assume that they were married in a church and the marriage was recorded there.
Somewhere I have read that Leatha Hamlin was a daughter of John and Nancy Hamlin, and that Leatha had at least two siblings: James Hamlin and Nancy Hamlin.William Warren Wrenn had two sons with the given name of James.(some significance?)John Franklin Wrenn had a son named James Landrum Wrenn (James for James Wrenn(John's father; Landrum for Landrum Carver(Frances Carver's father).My Sidney Wrenn had only two daughters; so no sons to name James.Sidney died in his 30's; his estate was administered by John who also was guardian of Sidney's children, including Mary Jane Wrenn Fox. John Franklin and Frances Carver had a son named, Sidney Thomas Wrenn. Undoubtedly John Franklin Wrenn was brother to Sidney.
Who was the brother of William Warren Wrenn who settled into the Louisburg/Raleigh area? Do you know the names of his children?
I have checked on the Wrenn, GA area, and have not found anyone there who harks from Person County. The Wrenns there seem to have a totally different origin. My wife and I checked through the area when we visited Georgia looking for some of her family, and I did check on the Gordon County, GA area for my Fox family where most of them settled in the period between 1840 and 1850; my Nathan Fox and his wife, Mary Jane Wrenn, came back after having two children born there, to settle on Thee Hester Road in Person County, right in the middle of Wrenn territory.
John Franklin Wrenn and Frances Carver lived in Granville County, for a brief period of their marriage, but finally returned to Person where they died. It seems that I remember a mention that John Franklin Wrenn was the one who moved to Wrenns, GA area, but that was not the case, according to my research.
John Franklin Wrenn was born ca. 1806; Sidney was born ca. 1807; William Warren Wrenn was born in 1812; so they were fairly close in age. The supposed father of these Wrenns, James Wrenn apparently had died before the Census of 1840, as he was not listed as a head of household in that inventory; and if the story about Mary Hamlin Wrenn living with the Thomas Wrenn and Mary Driver family in 1840 is true, then Mary Hamlin Wrenn survived her husband quite a number of years.
