Wish I had something to add. I'm in a Scots genealogy as a descendant thru my dad's mother, "The Mitchells of Kincardineshire" or some such. Mostly now, I just let 23 & Me and the internet do the work and find out stuff for me. Been contacted by relatives I didn't know I had - most recently a 2nd or 3rd cousin of my dad solved the family knowledge gap of how my great grandfather, a Polish jew, ended up being Harry Bailey...which has been a mystery for all 86 years of my dad's life. Also, thru my daughter's 23 & Me, a distant cousin contacted her and has the passenger manifesto from my mom's family journey (around 1940) from Germany (actually Portugal where they embarked from) to Havana and, subsequently, to the states...not so easy to find history when one parent is an escapee from Nazi Germany and the other descended from a Pole who fled the Czar's Army in the late 1800's. Mom's info mostly bombed into oblivion in WWII, great grandfather (as we now understand it) took his mother's maiden name to avoid getting conscripted - which was then "Americanized" (actually landed in Canada) on arrival.
I do wish I'd had the interest, 40 years ago, to ask my mom's father about the whole thing - she was only 6 or 7 (8?) when she arrived in NY, and mostly doesn't remember much (even less at 84, w/ Parkinson's) - other than the 1st grade girl who called her a dirty German, which she didn't understand at the time - because she bathed regularly.
Well, shoulda said nothing to add of importance. And I don't have the time to dig for more info - especially on my mom's side. They went to some length to bury their German past, given they left in fear for their lives and landed in a fairly inhospitable U.S., which wouldn't even let them in for about a year. Fortunately, they had $ and luck and toughed it out in Mexico City until they were granted permission.
Snark on, folks.
