I may be one of your pigment-deprived Caucasian cousins.My mom was Ann Glimp of Burnet County, Texas.
There is a small town north of Memphis, TN named Glimp, TN.It is just west of Henning and north of Covington.My side of the Glimps all settled there for a bit before moving to Victoria, Texas sometime around 1840.Apparently, even though slavery was legal in the Republic of Texas, they left the majority of their slaves behind in Tennessee.These black Glimps stayed in the Glimp/Henning area.
In the late 1950's or early 1960's one of my mom's aunts who had an interest in genealogy found Glimp on a map, made a detour north from Memphis, and attempted to find the town.Somewhere around Covington she stopped at a gas station and informed someone there what she was planning to do.They told her, "You don't want to go there," and then told her that despite her maiden name, "... you don't have any business there."Dissuaded, my great-aunt drove away.Years later, sometime in the 1970s, she drove back to Glimp and no one attempted to block her progress on this trip.When she drove into Glimp, she found out that the town was made up almost exclusively of "colored" (African-American) Glimps.
My mom's sister in Texas has a written acount of this story.If you'd like this or more information on the Glimps in Glimp, TN, please e-mail me back and I'll put you in contact with my aunt.
