Cumulus: i'm not a lawyer, but just wanted to say that I'm very sorry for you on 2 counts, about the loss of your parents & about you discovering that your father kept his other children secret from you. I can only imagine the shock to you, but believe me it is not uncommon, I have heard many such stories & have one of my own.

Please don't blame your half-siblings for anything, they are also victims of lies in this. I was a wife of a Turk too and not only did he walk out on me & our kids, but he never told his new wife about our children, he disowned his children for pure selfish & cowardly reasons. I don't know the reasons for your father's lies & secrets, but they were his lies, not that of your 1/2 siblings. Consider that you have gained & dicovered new family members, perhaps a small consolation for the incredible loss of your parents.

Best of luck.
