John McElveen (McIlvaine) - Where to Start

Here's what I suggest.
I have posted my DNA in Geni. I have also joined the mtDNA project for H1 [https://www.geni.com/projects/H1-C16239T-Mitochondrial-DNA/36277]. Apparently, there are no profiles on Geni with Mitochondrial DNA that matches Susannah (Harvey) McElveen Burnside Bragg. "Greater confidence can be obtained by testing close relatives of Susannah (Harvey) McElveen Burnside Bragg."

There are 4 generations between William Emanuel McElveen Sr. and John McIlvaine so perhaps we should first see what matriarchal samples we can find and how they fit with the McElveens? I'm given a link to find samples and wouldn't it be cool if we found a McElveen somewhere that took a DNA test. I'll ask FTDNA.
