Back in the day, when people wanted to publish Jewish scholarly books, they'd often need to get funding in advance in order to pay for printing costs. To do this, they got people to "subscribe" to their book--basically those people would pre-pay for a copy of the book, and in exchange, their names would be published in the eventual release of the book. These "prenumeraten lists" could contain your ancestors!
I was able to use "Sefer HaPrenumerantn," a kind of index to those listed in prenumeraten for about 800 books, to find references to books sponsored by people from Kolodne. And look who's listed in one of those books. (More information on how to use this book below.)
