What Yoko had to say about Maureen : Jeannette Caserta, who runs several beatle-related sites (Dark Sweet Lady, Beatle Children, Beatle's Wives & Girls (facebook page)), asked Yoko Ono on Twitter : 

Jeannette: Do you have any fond memories of the late Maureen Starkey (Ringo’s ex wife) to share ?

Yoko: She was a very intelligent woman and a wise and loving mother for her kids.

How sweet of Yoko. 
Especially when Maureen told a french reporter in 1988 that she always thought Yoko was strange ! lol
