Brother just bought another book called "The Celtic Realms" by Myles Dillon and Nora Chadwick. He tells me it is chock full of gods and goddesses and real human beings with -oc at the end of their names or in the middle. I found an Oengus Mac Oc, Irish god. This doesn't seem to be a coincidence. The -ac and -oc may have become ap in Welsh. Like most Celtic mythology it's probably boring. Gary
