I saw your note on Robert Lacaillade in Calif. I know that a Robert Lacaillade was adopted by my grandfather and grandmother (her maiden name was Lacaillade, Maurice was her father she was born in 1889). Robert Lacaillade took on their name Colmerauer. However I do not know when they adopted him as I believe he was born in 1925 or 26. He has since died, lived in Belton, Missouri. I was always told Robert's father's name was Maurice which I could never find anything on, i.e., census, etc... also a Maurice Lacaillade died in Modesto, Ca in the 70s....both can be found on genbank. Let me know what you think.
