My son's name is Andrew. I can't beleive it is in the top 5, I thought it was rather old fashioned. Anyway, it's my brothers name. I wanted to name him Rader Trygve after my great uncles but my wife vetoed that.
Oh, my goodness! I KNOW someone named Trygve! (Or at least I used to.) He's probably in his early 20s now.
My grandmothers both had unusual names: Gilla and Isola. Isola had a sister named Alura (who married a guy named Rome).
