Courtney, if you give more details about your grandfather and his family someone might know which family in the IOM he came from. If he is no longer alive could you ask your mother for his date of birth, or at least the year, and his date of death? Do you have his death cert which should give some details, depending on which country he emigrated to? Does his marriage cert give his parents' names and address? What date did he leave the IOM?
