I am just starting on my husband's side of the family. His mother was the great grand daughter of Jacob Feller (born December 1811 in Canton Bern, Switzerland and married to Marie Krebs). We also haven't been able to go any further back than Jacob. The family stories passed down were they were of German decent and that "Feller" came from "Fellers of Trees". I do have the complete decendant listing along with birth dates and places for all of Jacob's decendants up through my husband's generation. If you have anything to add to what I have, we would certainly accept any help you can give us.
