LOL...I have to tell you a smalll short story. My siblings have a different mother than I do. Tragically she died very young. Well we have been stumped on any information on her. My poor younger brother wants desperately to find family information. First he came up with...that she was an heiress and some sort of a conspiracy theory. next was just what you said. Maybe she was in the witness protection program. I finally had to step back and think clearly and not crush his ideas. He was basing his ideas on nothing in particular just desperate to get info. But I did laugh later when he couldnt see or hear me...lol.. Good luck. C
