I was adopted at birth and did not know it until my adoptive father died. I was in my 50's at the time and am now 63.I did find out that my birth name was David Lamar Chalfont and that my father was from somewhere around New Orleans. All I know about my birth mother is that her first name was Mary and she died soon after giving birth. I have a sister, named Jackie, living in Bossier City. Anyone have any ideas?
