Clarence: I am a direct descendant of Abner McGarity (1780-1832). He was my GGG Grandfather. Your father's social security application can be obtained from that agency, and it would at least list his parents, workplace at the time, etc.. This is a good place to start. I do not have a J.P. McGarity in my FTW file. With his parents' names, however, I may be able to be of some assistance to you. Good luck.
