 Echmarcach mac Ragnaill may or may not have been Gofraid's grandson, as he is also contended to have been a grandchild or great-grandchild of Ivar of Waterford.The same is the case for Cacht ingen Ragnaill, queen of Donnchad mac Briain, often assumed to be Echmarcach's sister.The "Banshenchas" record that a daughter of one Gofraid named Máel Muire married Gilla Pátraic mac Donnchada, king of Osraige.
