Of course! Until someone points out the obvious, you don't think of it. I just "knew" she was Oma and didn't think about it, although I did wonder how they made Hattie into Oma. I have heard people use Oma before, and this family spoke "Low German". They were originally Mennonite (and perhaps some branches of the family still are), and very likely of similar origin to the other Berkey family, the one that is traced back through the LDS records to the Burgi's of a Swiss canton, and who were Anababtist. (it may be the same Burgi/Berkey/Barkey family, but so far there is a missing link in the late 1700's). Aunt Oma returned to the Indiana area, where her father and mother had come from, and may very well have taken on the German word. Thanks.
