I think the contact page Sylvia linked would be the best way to contact them. And I'm sure they (or someone from their family ) will also see this thread.
On the subject of GP assignments next year, I don't think it will be a problem for them to get at least 1, if not 2, even if 1 is SA. I believe countries can invite who they choose, as long as the basic guidelines are followed so that everyone gets the min number of spots they are guaranteed. S/B are well-known, so I'm sure they'll get an invite outside of SA. Kimmie Meissner, for example, got 2 GP assignments last season and was not in the WS top 12 - and she did not compete at '09 Worlds. I know she was on the SB list, but technically, she was only guaranteed 1 assignment (I think).
