May I make a suggestion to help all of us sort out the growing pile of information available?
I believe it would be so much faster and clearer if each of noted ethnicity and religion of the relatives we are seeking. For instance, my DALKE [and spelling variants] were largely Roman Catholic, Poles from Poznan. I know from researching that there are many people looking for DALKEs with German-speaking Lutheran heritage, or Mennonite heritage. I certainly would appreciate this added bit of information if others have it. And I am going to add it to all my posts to help out others working with the same or similar surnames.
