Hi alipal,
I have a copy of Emile's death certificate if you would like it. I would love a copy of his marriage certificate. I also have his birth cert (in French) and a photo of Annie his second wife, my Great Aunt, Emile and two of the children. I have not been able to access the letters you mention about Agnes asking for money after Leo's death but keep trying to get onto that sight.
I will send you a private message with my email address as it will be easier to keep in contact that way. Please let me know if you receive it.
Pauline
