A few years back I found an on-line source for "prenumeraten." Just to enlighten those who don't know, before a sefer was published years ago, it would seem that feelers were sent out to find out who in the various Jewish communities would be interested in purchasing such a sefer. So these lists were published "somewhere."
It is apparently a useful genealogical resource, and thanks to Daniel Polakovic of the Jewish Museum in Prague, he was able to find my grandfather (Rabbi Leopold GOLDSTEIN) in the town of Kezmarok, Slovakia, on one such list of prenumeraten a few years ago. These lists were not always 100% correct, since they misspellings, etc., but one can figure them out.
I would like to see if his name (or any other friends/family members) appears on other such lists, but can no longer find that source, despite having "googled" to the best of my ability, and I'm a pretty good googler!
So can anyone help?
Thanks in advance.
