Names with the same letter

ggggxxx
So my brother started this in my family. He has 3 kids, 4th on the way and all of their names start with an "A" my sister took on the tradition. She has a daughter & her name starts with an "E" & the names she picked out for her future kid starts with an "E" I'm planning on doing the same & my sons name starts with an "X" (so complicated to find cute names with an X) ANYWAYS do any of ya do this? Or did your parents do this? I think it's really cute lol.
