Many individuals who have posted on this site are descendants of Rebecca Neyland Mask, wife of John Mask, of Claiborne Parish, Louisiana. Despite much hard work, proof of the identity of their parents has remained elusive. We know from records in Claiborne Parish and the 1850 Census that Rebecca's mother was Charlotte Neyland, born ca. 1775 in Virginia. Some researchers have assumed that Charlotte was the widow of Henry S. Neyland of Burke Co., Georgia, who appears on the 1820 Census of that county but disappears from the census subsequently. To my knowledge, no one has provided any data to back up this assertion.
While nothing is proven absolutely, I am going to make the case below that Rebecca was the daughter of Charlotte Dupree of Jefferson Co., Georgia. Charlotte was the daughter of Revolutionary Patriot John Dupree, Jr. of Jefferson County and his wife, Rebecca Wyche Dupree. John died 1805 in Jefferson County and Charlotte is listed in his will. This line of Duprees is ably documented in the book "A Dupree Family History, Some Descendants of Thomas, John, and Lewis Dupree, Emigrants to Virginia Abt 1700", by Rev. James William Dupree of Americus, Georgia.
The first record of Rebecca Neyland appears in the 1827 Georgia Land Lottery, where she is listed as a resident of Jefferson County (not Burke) and is granted land as an "orphan" in Coweta County. This is definitely our Rebecca as her husband, John Mask of Sumter Co., Georgia sold the land in Coweta County to William Dupree in 1837, after their marriage (Coweta Co. Book E, Pg. 236). In a separate entry in the 1827 lottery, the "Orphans of Henry S. Neyland", residing in Burke County, Georgia, were granted land in Muscogee County. These orphans, Elizabeth J. H. Neyland and Mary H. Neyland, sold that parcel in 1843 (Muscogee Co. Book C, Pg. 245). At the time they were residents of Richmond County, which adjoins Burke. The 1850 Census of Richmond County includes a Mary H. Neyland, aged 50, born South Carolina, with an apparent daughter, Elizabeth, aged 23, born Georgia. No sign of a husband. In a separate household is another Elizabeth Neyland, aged 35, born South Carolina. I believe that the above evidence strongly indicates that Mary H. Neyland is the widow of Henry S. Neyland, not our Charlotte.
Why do I believe that Charlotte Neyland is the daughter of John Dupree? First, John lived in Virginia at the time of Charlotte's birth and had a daughter, Charlotte, per his will. John Dupree and his descendants lived in Jefferson County, Georgia, where we know Charlotte's daughter Rebecca was living in 1827. Many of the descendants of John Dupree moved from Jefferson Co. to Sumter Co., Georgia, as did several Neylands, the most prominent of which was David O. Neyland (David was not Charlotte's husband). As we know, Rebecca married John Mask in Sumter County. In fact, John sold the Coweta Co. land to a member of this Dupree family< william Dupree. And finally, descendants of John Mask and Rebecca Neyland Mask evidenced considerable confusion about Rebecca's maiden name in their reminiscences. A number of them claimed she was a Dupree, not a Neyland. This is understandable if Rebecca was the daughter of Charlotte Dupree Neyland and strong family ties with the Duprees persisted after Charlotte's death in Louisiana 1850-1860.
I invite others to pursue this line of research and post their findings here.
