I like the way that
Lindsay and
Lindsey sounds and the way how it's written. I generally don't like -ey names, but
Lindsey is one of few exceptions. Hm, I didn't hear of any boy or man with this name in whichever form, or maybe I just forgot of them. I prefer it on a girl, though I don't think it's a bad idea to name the boy
Lindsey or
Lindsay. But if I had to name my child this, I would choose
Lindsay if it would be a girl and
Lindsey for a boy. I think it's just more pretty.
