Preston, check out the Stidham Rolls of 1886, Creek Self Emigrants.
Exhibit S, Silas gives testimony for his uncle Dick McNac. (Remember the Stidham rolls are about Creeks who emigrated from Alabama at their own expense).
Also Silas Jefferson was listed as 1/2 Creek on the By Blood rolls, his parents were Jeffrey Manac and Betsy Manac.
Preston Silas's history in the Creek Nation is long and well documented. Though much of that history is written in Mvskoke langauge, its still there. Angela has turn me on to this guy, he was a hero to luste-cate Creeks. And a hero today.
