Great to have read your message today, and I must apologise for having taken so long to find it.
Anyway, I found out some details of the second marriage from our cousin Derek, son of Francis, WJL's first son of his marriage to Isabelle Hélène Béart.
Derek sent me some nice information at first, but then suggested I contact his sister Peggy in Buenos Aires.She was tremendously helpful and I have kept her posted on any new info I managed to find.
In the meantime I also made contact with our other Argentinian family, this time on the side of Walter Malcolm, only son of WJL from the first marriage, and brother of my grandmother.He emigrated to Argentina at about the same time as my grandmother and her sister emigrated to Brazil.
This other Argentinian family is also large, and I have corresponded with many of them.
Check out my website dedicated to Walter James: www.walterjames.leckie.nom.br (yes, it's a .NOM, not a .COM).
there is a list of descendants there, and some photographs. Click on "Descendants" and go on from there.
