Dear Ben, It would help those of us who have a lot of Fatherree information to share if you could fill in some blanks. Is Fatherree your grandmother's maiden name? If it's her married name, who was she married to? Does she know his parents' names? My advice is to talk to your grandmother and take notes carefully about what she says. Then e-mail me privately (email@example.com) or post again and I'll try to help.
