I don't know if this will help. My grandfather Meinrad Joseph Bisig came to the U.S. in 1879 at age 3 mos. He was born in Einsiedeln, Schwyz, Switzerland. His father Jacob Anton Bisig was born in Willerzell, Schwyz, Switzerland in 1845. I have my Bisig line back to 1599 and have done some work on the Bisig's of Einsiedeln, although there's more to be done. Let me know if I can help.
