Traditional, modern etc;
Like, I know three girls called Kayleigh, two called Kayley and two called Kaileigh and a baby girl called Kailey. It's quite common in the USA, where we are. I personally like Kayley and that's all.
Or Aaron. I like this spelling. My (Jewish btw) ancestors spelt it Aharon, and I've seen some people around other sites called Aron or Arron.
And then names like Susannah. My spelling. Susanna, Susana, and more.
Lukas and Lucas
What sort of names? Modern spellings, traditional spellings, any other things?
