I am trying to find my ancestors, with no luck.

My grandfather was Jules Blair Guillory married to Mary Lee
Parker of St. Francisville, he is from Ville Platte. His parents are supposed to be Archille Guillory and Ena Marguerite Ortego of Evangeline Parish, but he is not listed
as one of their children. I know one of his brothers was a doctor, and that is all I know. Oh, one of his brothers was
Dru or Drew Guillory married to Rosalie Deshotel.
