Ken, you are correct about a trading post. The story I have heard repeatedly is that Samuel opened a trading post not long after he arrived. It was probably several years afterward that the venue was given a name. It is very possible the name Fishertown became popular because of William's store.
There is so little information available on Samuel and those early years that I don't think anyone can say for certain. However, we were always told that Samuel was the founder of Fishertown. Maybe someone will read this information and provide some details. Apparently the name of his Indian wife is not known and was not on her headstone. However, the Indian roll number was passed down. Most of my siblings including me are registered as part Muscogee (formerly Creek) Indians with the BIA.
I'd certainly like to get more information, but I would probably have to contact W.T. Scott's branch of the family to learn more. I was told that he gathered a lot of information when he was researching for the Family Tree back in the 1950s. Someone may still have his notes.
Anyway, thanks for responding.
