The other week, I was asked to lead bentshing in shul after lunch. We were using the shul's shiny new own bentshers, and I saw they lacked the four lines beginning תהילת ה׳ ידבר פי after the introductory psalm; but I launched into them cheerfully anyway. "It's not the German custom to say these," said the rabbi. "So sue me," I riposted; "I'm a Litvak!"
Well, I got the laugh I was after out of that, but afterwards it occurred to me I'd never sat down and worked out how much of my ancestry came from where; so I did, and here's the result, as far as I can trace my family back, with each concentric ring out from the centre representing one generation back in my ancestry from myself at the centre, and an alternation of males and females among my ancestors clockwise from the top.
(Some of the outermost rings are a bit tentative; and in places I've interpreted a vague "Russia" as probably meaning the Pale of Settlement—the part of historical Poland that came under Russian sovereignity following the eighteenth-century partition of Poland, and to which Catherine the Great, who had suddenly acquired a large Jewish population, and didn't want them dispersing into the rest of her empire, legally confined the Jews.)
(All my ancestors, as far as I can trace them back, are Jewish, so this only shows country of origin, and regional Jewish cultural tradition, not ethnicity.)
