We don't know the sex of this baby yet, but if it's a girl we want to name her Lucy after my grandma. We thought it would be nice therefore if her middle name was one of Dh's grandmas, and have opted for Catherine, who was always called Kate. So should we use Catherine or Kate? I actually prefer Kate, but I don't know if Lucy Catherine "sounds" better somehow? Opinions please? Surname begins with P if it helps.
