Back in 1999, I received a Davoren family tree from a women in Australia (I think). Her name was Margaret. I couldn't find any connection to her line. After reviewing the file she sent me...it seems you two do have a connection. I will post her email address to you privately as a courtesy to her.
Please tell her I sent you....
