Pronunciation of Leith?

Is [name_u]Leith[/name_u] pronounced “lee-th” or “lay-th”?

I like the look of the name and it would be for a girl. I prefer one pronunciation over the other but want to know exactly how to say it!

My first reaction is “lay-th”, but I don’t know for sure.

I would say [name_u]Lee[/name_u]-th just like [name_m]Keith[/name_m] with an L.

I would pronounce it like [name_m]Keith[/name_m] but with an L instead of a K.
