Wren Eilley - I like this
Olyvia Jade - I love the name Olivia. However, spelling it Olyvia doesn't make it unique, it just makes you look illiterate (sorry!) and she would spend her life spelling it to people
Willow - Really like
Grace - Never been a fan of the Grace, Faith, Hope names
October - cute and unique
For a boy:
Legend - A very big name to live up to!!
River - great, although I do prefer it on a girl
Scout - again, prefer on a girl
Liam - bad associations, not a fan, fine name though
