Lynnie, sorry if I come across as critical (and can understand getting dislikes) but you provide a lot of very detailed information about your cousin's life that would likely identify you to those who know him. That may or may not be an issue for you. I've got no reason to doubt you at all.
However, correct me if I have got this wrong, it does sound like you are not concerned about his finding you are posting details of his life online.
We've often said to posters be careful what you post about your life or the lives of others you know - especially on a publically accessible forum.
