Porche Family In Baton Rouge

I am looking for any informatin on the Eugene POrche family. They were in Baton Rouge in 1910 and his wife Susannah was listed as widow in 1920. Children were Ophelia born 1878 and Francina who married a Henry Franklin Thompson and a possible daughter Nora who married a unknown Rene and had a child name Theophilus Rene born 1909 . Any help at all greatly appreciated.
