Hello. Very briefly, I do have information on Repp sources. My own line originates in the Saar and Alsace border. During the early 1700s, this group, under direction of the Austrian-Hungarian Emperor--settled the Banat Plain--in present day Rumania. This was the second major attempt to make this part of the empire more Germanic and Roman Catholic. The first wave were the "Danube Schwabians"--and this name was also adapted to this later wave. Due to their initial presence near the French border--many of these immigrants could speak both French and Germany. Crepes and kraut were both family recipes passed down. Literacy seems to have been focused only on religious matters. Farming, as always with Germans, was ubiquitous. My own lines left this region to settle in Michigan in the early 1900s. Repp--from this line--derives from a German word for a wine-maker.
