(Take this for what its worth)
An ancestor of mine was there from the english isles at the time of the Kahn, he joined the army; which as an adventurer he was prone to do.
He fought so well and he was valued so highly that he was given one of the khans daughters as a wife.
so, i have relatives (maybe) still living there.
i have relatives in Japan, Germany, Russia, England, (barf) China, (barf x 2)
I had a 1200 page ancestry/list for many years.
My father wrote it all out for me. (I had a friend who was an antiquarian who wanted to read it, he died and his wife has never found the book.)
i still have a short form of just the english/german/american family from 1406 to the present.
Also, it is a matter of self preservation as a i have about a dozen assholes out here that want to terminally inconvenience me.
( i was "cruel and insensitive" to them)
Such is life.
BTW, 70 year old "wizards" are not uncommon, i know one who is 92 this year.
