The term "progenitor" indicates a person that is an originator of a line of descent; an ancestor, parent or precursor. I've kept track of all the "beginning" lines of the various families that have been researched. Below is an alphabetical list of those individuals, while some have only a few descendants, others may have many. In time this list should grow smaller as we find more connections with the families and their descendants that bear the Scholderer surname and it’s variants. Please take a minute and look through some of these individuals to see if you know of any further connections to any of ancestral lines.
