I picked y's with i's, apostrophes, and adding letters.
I don't mind when all kids have the same first letter, well, since Husband and I are both D's, we might just make everyone a D. Depends, really, on if we every have kids!
I like boys names for girls but I can see how this can get old. I worked with a Kyle who was a girl and also a Daryl who was a girl. It helped their careers because frankly, people thought they were boys on their resumes.
I think you missed my WORST one, made-up names. Marvcus, for example.
