My wife, Brenda, passed away in 2009. I have her computer files and will share whatever information she has documented on the Bertaut family. After reviewing her records I can't answer your question on whether Pierre and Auguste are related. Her records on Pierre are sparse. Her records on Auguste are more plentiful. I'm not really comfortable with useing this site for communicating family information. If you will send me your email address I will give you informtion on the Bertaut family.
