thanks for the list of children of Alfred. I think we have right and complete this time.
As far as our association is concerned, I must say here that it's about Ducharme from the Charron-Ducharme family. Of course, anyone can become a member, if he/she has an interest in these families, event if he/she is not related to them.
As I don't want to mix the association with this forum, I will answer your question about books or CDs in an email I will sent to your own address.
