Marshall, you already spoke to me and my Martin/Spencer cousins via email. I know you have no surnames I have in my direct line on record even though I have some cousin DNA matches with Spencer, Sherill, Robinson. These surnamesall are related to my Martin line of Burke even though I dont have these surnames in my direct lines on paper.
You have Y-DNA on your Locke?
The DNA tests we took besides Y and MT-DNA are family tree DNA family finder test and the ancestry DNA test. These test are different than Y and MTDNA. These tests help find cousins that share the same DNA that you inherit from all your ancestors through autosomal DNA and can go to any side of your tree. This is a much harder test to figure out than Y and MT DNA. We have cousins on this test we can confirm through paper as our cousins but most of our matches we can not confirm. Our Gedcom at this point is pretty much useless. We only have 2 male Y-DNA lines that actually match to other people of same surname. I have two y-lines that don't match surname and match to surnames we have no connection to on paper through direct lines or cousin lines. We still have several that have not Y or MT-DNA tested but in general have several lines known to have gotten their mother's maiden name and have unk fathers.
In general there are a lot more people from the south that have tested at ancestry than Family Tree on the autosomal tests. Some people have tested both. Most people in the south will get anywhere from 1000-4000 cousin matches. We don't. my uncle's matches only total 200 and mine 170 at ancestry. We actually have more cousin matches at Family tree. I have 220 and my uncle just hit 300. Most are distant relatives that we cant connect paper to. I have no close cousin matches but my uncle has a few. His close matches either came from Western NC, A few enrolled Cherokee, a few documented on the trail and some were just our neighbors and we have no idea why or how we are related only that these matches have connection to the Cherokee and some of these matches came out of Abermarle VA. We also have distant matches that came out of Abermarle but again we cant trace out of NC at all on paper. Leaving out that we have one Mex line our matches are very few compared to others tested in the south and some of our few cousin matches do include a few Tex/Mex matches. One of my uncle's closer matches is Caddo and their family like ours is both Tex/Mex and SE and at the moment we can't come up with a common ancestor.Im trying to help them with their Mex line and maybe we can trace it back and hopefully it leads to my paper trial somewhere. This person is around my uncle's 3rd cousin. We should be able to figure out 3rd cousin but at the moment we can't
AI got their Euro surnames either by taking a name, inheriting their name through a Euro line and some were grabbed and baptized and forced to take a name (like our Mex lines). There was also AI slavery before African slavery so some way back could have gotten their surname from a slave master. Researching AI or African it not easy. Just like I asked Juanita about the Sneeds. People believe Jacob Sneed of Burke county was the patriarch of the Cherokee Sneed but Cherokee apps dont go back that far so the world may never know if Jacob Sneed is in fact the patriarch of the Cherokee Sneeds. We only know Jacob Sneed was living around people connected to General Joseph Martin.
You might try taking the ancestry test and or Family Finder test at family tree. If you can, take both. Some people only test with one company but since we tested at both there are people from our area testing at both companies so this may help you research. Especially if you match other people at close range that you can confirm on paper are your cousins. The test so far has at least helped us with the known cousin matches we have. My uncle has a few closer cousin matches that are confirmed happen to connect to our Eastridge line somewhere through our Eastridge or his unk wife. My uncle got a cousin match to one of our closer cousin Martins that left Burke and went to TX and AR. He has another closer match to our Piercy/McMillan line of Burke. All his confirmed closer matches are 3rd cousin or 3rd cousin once removed. At least we know our paper is accurate to a certain point. Now with the confirmed matches I have to figure out what 3rd party matches we all may share that we cant figure out.
My Tex/Mex aunt that married Brown in VA . My aunt's husband on the 1910 census Snow Creek, Franklin VA has his parents as Billie and Pearl Brown both born VA 1800's. According to two trees on ancestry this Brown family has been in VA a long time so I dont know if they are related to any Burke/Wilkes Browns. This is where Y-DNA would come in handy on having someone Y DNA test your Brown line. Its too common of a surname. Family Finder and or ancestry test may also help should you happen to get several matches to brown from a common area.
