Not sure how I didn't see this until now, but I think I may have my
answer >from the JRI-Poland SIG.
I found what appears to be the family in records in Krakow births, and
it claims the maiden name was KRONGOLD. Since those records come from
actual documents, I'm assuming I can trust those as valid sources. I
will assume the maiden name of KRONGOLD.
If anyone has anything to add to this, please let me know.
