Hello,
I have Kindle/Kendall relatives who married into the McAdoo family, I'm unable to locate the info that I have on this right now, but I will keep searching. I do remember that there are some McAdoo's buried in a cemetery that I've visited in AR. This may be info that you already have, let me know if you are interested, and I will keep searching.
