Some years back, when stated learning about my ancestors, Manning of Ballyteigue, Rathdrum Co Wicklow, Ireland, I was introduced to naming pattern. My gt. grandfather was named William, he had been given this christian name on the death of his oldest brother who had died just before he was born. Who was my gt. grandfathers father ? I said William, for if the 1st son, William was named after the father's father, this would mean my Gt Gt grandfather's christian name was William, but no. later found that my gt grandfather married twice, his first born son was named George, therefore GtGt granddad name was George. All this was verified my his will A trap for the new. Dave
