I have Maryland Carroll ancestors myself, no known connection with the Carrollton Carrolls that I’ve been able to find and burned counties up there (1812) will likely prevent ever figuring that connection out. I’ve got seven confirmed in the Rev, many other reputed to have been but pension apps no help, so I’m stuck. Haven’t worked very hard at it for several years, genealogy is very interesting until you’ve been pounding your head on a brick wall that just won’t give for a few years.
Those brick walls always tease you. You’d think two Maryland Carrolls would be related and it keeps you hunting. I looked for a link between my SC Carrolls and the Carrollton Carrolls but didn’t find anything at all. In addition to distance the Carrolltons were Catholics and my line were most likely Presbyterian so any connection was doubtful from the start. But you gotta look...
I have Lee ancestors in 1600-1700 North Carolina including a Robert Lee, but there is no link to the Virginia Lees. Just the old genealogical tease.
One of my Huguenot bunch was a business partner with a Thomas Jefferson, who turned out to be the grandfather of the one we all know. Not sure how good that partnership was since they were suing each other, which is why I know about them.
