Greetings from Indianapolis.

I hope that somebody reading this is a good detective!!
Two cousins, both named Anna Trachsel married brothers, they all were from Steffisburg, Switzerland (I think ?). Anna Trachsel (1609-1680) married Nicholas Yoder. Anna Trachsel (1607-1666) married Yost Yoder. They all were Amish/Mennonite. Both couples were married on the same day, 10/14/1642; I don't know if it was one ceremony, or different ones. I don't know the parents or families of either of the Anna's. Anna and Yost are the 10'th gr grandparents of both my wife and I. Can any of you help me find the families of these two cousins?

Thanks ahead of time for any help you can give,

Dennis Buerge
