Gloria Jones

Dear Mary, Have read all your books, they are my absolute favourites, in fact I wait a while and reread, which is great because I feel as if I am going through the family history of each series. Just one question, in Someone to Care, Viola is said to be older than Marcel, however on the family tree in the next two books he is shown as older by two years?.
I have your latest book on pre order already, I know it is the last in the series so I will left wondering about Harry Estelle and Bertram who I think are such interesting characters
