The cemetary I told you about in MS where Lucinda, James, & John are, is Officially named "Blocker Cem." but locals call it Blocker-Trant cem.
I believe My Ggrandfather either had relatives or knew poeple in Grimes/Brazos county's when he migrated there from MS in the 1880's. They initially settled near Democrate crossing on the Navasot.
Got a hint about DB Carroll's father may be Abnor Carroll, 1830 Census, Walton County, GA.
