Hello, bluedonna, and welcome to Psych Central! If your mother was really young, then she might not remember a lot. Plus, it is something that families don't like to talk about.

My husband's grandma and one of his uncles committed suicide, but the family never talked to their children about it. I think depression ran in their family.

Off hand, I see nothing wrong with asking one of his classmates about him. Just don't let your mom know. At least that's my thoughts.....
