Thanks to everyone who has emailed me about Antoine and his ancestors since I originally posted here.
In the 10+ years since I posted my original message, I have traced my Berard ancestors all the way back into France. In an attempt to share all that I have found, I've posted much of the info on a website dedicated to James Berard, Antoine's son. You can find this information at: http://www.richhall.org/berx.aspxhttp://www.richhall.org/berx.aspx .
Also, I'm not sure my email address from 1999 is still valid. Instead, you can use my contact page on the website to send me a message. It should always be able to locate me regardless of what email address I'm using. The contact page is at http://www.richhall.org/contactus.aspxhttp://www.richhall.org/contactus.aspx .
