I am attempting to research my mother's ancestry in hopes of finding the answers to our BRCA1 mutation. Her maiden name was Dawson, and her mother's maiden name was Sivey.

I can trace back to Maria Catharine (Guenthuer) Sivley who was married to Joseph Zieffle or Zievely--which was eventually changed to Sivley or Sivey. They were born in Germany and resided in Pennsylvania and Virginia.
