Failure to Mention Does Not Mean Failure To Exist

Your relative may not have mentioned all his children in his will. Some wills will include a statement naming specific children who have been "left out" of the will saying they receive nothing or only giving them a token amount--which serves the purpose of indicating that they were not forgotten by the parent. But other wills will include no such clause mentioning "disinherited" children. They may simply be not listed because there was a falling out with the parent or the child had already received their share.

Don't assume that your ancestor named all his children in his will. It's possible that he didn't.
