One thing I may have forgotten to mention is that it was always taken for granted that my GGm (Frank's daughter) was of native American heritage. At least that was the family lore. Turns out no one shows even a trace of native ancestry. NOBODY.
Where that story started I do not know. But even my living Uncle agrees that he was told that. My father used to explain his skin tone that way, even though it wasn't red (like native or in some cases, related Nordic), but olive.
Frank was right in the middle of the quadruplet of children 1 year apart.
I truly believe the possibility exists that Frank was a foundling, orphan or otherwise adoptee whose heritage may not have been known, but his coloring may have given rise to the mistaken identity as NA.
That might explain why Med shows up rather than Native.
It's another theory to heap onto the pile, at least...
