I too rechecked and found two Samual's: Samuel Moses Fisk b. 08 May 1878 and his son Samuel M Fisk b. 1903 both born in Alabama. Ref: 1880 US Census, Beat 12, Madison County, Alabama.
It seem my line moved from North/South Carolina to Alabama and then to Texas, farming the crops in season. My father was a produce farmer The others I'm unsure of but likely cotton in Alabama and grain in NC/SC Carolina.
I would love to find a solid link where my line came from Ma.
