I am also descended from Martin Fehrenbacher and Anna Maria Bohm. I'm not at my computer right now so I don't have my info in front of me, however, I'm assuming, if you are living in the US, that you are descended from either Augustin or Michael Fehrenbacher/Farabaugh. I don't remember off the top of my head if they are the children or grandchildren of Martin and Anna. Anyways, I should be able to get back to you in a few hours with some better info. I just thought I'd let you know that I'm willing to share anything I have.
