I think the Church needs to insist on at least one saint’s name. Once upon a time, this was virtually a requirement. I’m not sure how official it was, but I do know that prior to Vatican II, a priest would have insisted that least one of the names to be that of a saint.
My parents were expecting only one child when my mother suddenly produced twin girls. If it was a girl the name was going to be Nancy Ann. They had to scramble and ended up with Nancy Lee and Nadine Ann. My sister regularly refers to Ann as "her saint."
Oh, they certainly did insist back in the day (1943). My own mother was supposed to be named Carolyn, but Father flat-out refused to baptize her with that name.
My mother’s godmother and godfather took her to church on the day she was born (at home). Her godfather was about to be shipped out to the war and they wanted to get the baptism done before he left. So off they went, in the dead of winter, and walked over to the church. That’s when Father made his pronouncement.
He said he’d baptize her Carol Anne, but not Carolyn.
Rather than traipse all the way back to the house, Aunt Jean made a Command Decision. The child would be named Barbara. And so it was.
Grandma was surprised, but my mother loves her name.

My maternal grandparents named one of their daughters Doris Mae, until they took her to be baptized. The priest told them that ‘Doris Mae’ was a name for a showgirl, and he changed it to “Mary Ann”, even though one of her older sisters was already named “Mary” But from then on, she was called Mary Ann by the family.
