I did get the reply, thanks. It gave me some more info that I didn't have. They were listed as owning the house in their single names so I didn't know they had married. And yes, I saw the property transfer where Sheri's mother acted as her representative in the sale.
Thanks much - still would like to know why she died so young. We all ran around, boated and skied together back in Ft Myers in the 70's-80's.
