Help! I'm listed as my great grandfather!

Add an identical brother of Jack Hiawatha Dowdy, Sr and a curator with access I can use that profile to replace your current profile.

BTW: Private User - If your name is Jack Hiawatha Dowdy, IV I can just switch those two profiles directly.

OK, Private User, I have made the switch.
Please check.

Her old email cold still be used as a login, but since she does not remember the password I have removed the bound mail to enable you to re.invite her with a new email.
