The term "progenitor" indicates a person that is an originator of a line of descent; a 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 the families that bear the Scholderer / Scholder name. Please take a miniute and look through some of these individuals to see if you know of any further connections of ancestral connections.
