Welcome to the DAVAL message board.
The DAVAL surname is in my husband's family tree. His ggg-grandmother was Anne Josephine DAVAL, who married Nicolas RONDOT circa 1830 in France. I also have a LAMAR ancestor who married into the "DuVal" line circa 1700. </P>
If you find or have a "DAVAL" website on the Internet, send me the URL and I will post it under Links and Announcements. By sharing information we can help each other build our family trees.
These are some variations of the surname DAVAL that I have encountered in my searches: D'AVAL, AVAL, DUVAL, D'VAL, and of course DAVAL.
Good luck with your research!
