Dennis Callahan claims to be a "fourth generation hereditary witch."
His great-aunt Marion was born with a veil, what is referred to in medical terms as a “caul.” It’s a hood of porous skin that covers the head of a newborn. It’s extremely rare to be born with a caul, which, for many, indicates a “third eye” or heightened psychic ability.Marion's niece—Callahan's mother—married a man whose sister was a witch.
For the past 400 years, his ancestors have been witches who read tarot. But Callahan’s pagan ancestry stretches even further back to the Druids, who practiced a type of paganism unknown today because they didn’t write. [Link]I will not criticize the claims made in this article for fear of waking tomorrow morning as a toad.

I've heard of families like this. They perform hocus pocus genealogy :D

Some of my ancestors didn't write, but I never suspected they were Druids until now.
Generation is you, your parents, their parents, etc... your mother, her sister and your father's sister is only one generation; at best he can only claim two generations....
