Oh my, I would have never guessed Sebastian! But now that I know, I can see that the first letter is the same as in the Schottek name. Thank you so much.

I had come up with Kollibal and Nollibal, but got no hits on either. Kolibal is a Czech name, so that must be the equivalent.

Next question: is Sebastian's wife's name Anna Schottek? If so, do you think brother and sister married sister and brother? The couples apparently continued to live in the same house, 23, for a few years. Then Andreas and Rosalia moved to house 26 about the time the first set of twins was born.
