I've recently hit a dead end at the 14th century on one of my lineages with Arnholt, ap Gwillim, esq. and Gwillim, ap Meiric, esq.
From my understanding, ap or ab means "son of". Is this correct? In this case it'll be Arnholt, son of Gwillim, son of Meiric.
What is the proper method for adding these names/titles to the family tree? Should "ap Meiric" be in the description or should it be part of his last name?
I have more info to enter, but I don't want to continue entering names incorrectly!
