My niece is named
Ashleigh and my nephew's wife is named
Ashley. When one is writing about them the spelling differentiates, but in speaking it can be confusing and the family tends to add the middle name (
Ashleigh Marie,
Ashley Suzanne) to make who one is talking about clear.
Ashley is so common in the USA in that generation of young women that no one in the family has ever thought this was "weird" in any way.
