Robin, yes I think J.P is Joseph Pleasant Sale, brother to Adolphus John Sale.I think Tom Sale, III who reads this board may have more info on him.
I have some notes that I got from Tom which indicate "the 1850 Census of Troup County, Georgia lists Joseph P. Sale, 28, a farmer by occupation, with a 20-year-old wife (Ann) and James, a one-month-old son. By 1860, they were in Louisiana. The story I heard was that they came by wagon, with a group of other families. Some of Joseph P. Sale's older brothers had already made the trip, settling in Bienville Parish." One of those older brothers would be my 2nd g-grandfather.
Claiborne Parish history states about early settlers, "Township 23, Range 8, was proclaimed in 1839-James Ward making the first entry on Section 10, in December of that year.Cornelius McAuley entered land on Section 31 in 1847.Isaac L. Leonard, J. C. Garlington, Peter McDonald, James C. Beck, J. W. Camp, J. P. Sale, W. T. Leonard, James C. Taylor, Redick Aycock, Lewis Moore, Joel G. Patrick, William E. Hughes, A. J. Watters and perhaps a few others located lands here during the years 1850-56."This is near property I still own.
Also, the 1866 enumeration of school aged children in Claiborne parish list J.P. Sale with 3 boys and 1 girl.
I have Joseph Pleasant's birthdate as April 10, 1821 and his death as August 18, 1870 in Haynesville, Claiborne parish, Louisiana.He is buried in Old Town Cemetery in Haynesville.
I'll keep you posted if I learn any more.I find these Sales elusive.
