Surname Saturday - Finding the Parents of John P. Gibson

It's been over 10 years since I began searching for the parents of my third great-grandfather, John P. Gibson, and each time I post the surnames I am researching, his name always appears at the top of the list. Without a doubt, John's ancestors have been the most challenging to find, but I am certainly not ready to call off the search.  I do have some pretty useful information about John, including the year and place of his birth (1799 in SC), a copy of his marriage record to Margaret J. Williams in Aberdeen, Monroe County, MS on January 3, 1843, and a copy of the marriage bond posted by Joseph Gibson, whose relationship is unknown.  Thanks to the U. S. Census recorded in 1860, I also know that John P. Gibson and Margaret Gibson were living in the Cherry Hill area of Calhoun County, Mississippi, where he worked as a blacksmith.  According to that census information, John and Margaret Gibson had seven children whose names were Elvira, Malverda (my great-great-grandmother), Francis, Asberry, Sarah, Mary, and Martha. I also found Calhoun County land records showing that John sold his land there and moved to Carroll County, Mississippi, where he and his family were enumerated on the U. S. Census of 1870. Although John most certainly died before the next federal census was recorded, I have been unable to locate either his burial place or where Margaret is buried. As I write this post, I am hoping that another Gibson researcher will read it and have information he or she is willing to share. But until then, I will do what I have done for so long - continue the search for information about John P. Gibson's parents.
