I have been trying to research my grnadmothers family history for some time now. I seem to dead end at the same person every time. I have had a few people look for me but they also dead end.

I am looking for the ancestors of William Barker born 05/26/1846 died 05/09/1916 He lived in the Saint Landry Parish area of Louisiana. He married Armid Guillory. He is the son of "" Gordon"" Barker( the dead end). (He has one son "william" Robert Lee Barker. My grandmother is not sure of her fathers actual name. He lived a life of wealth and obscurity.)
Can anyone help me
