Laura seems the most sensible option and I do love the name, Lara used to make me think of Dr Zivago which I read when quite young and loved but now kind of makes me think of Lara Croft which I don't like as much. Lyra I really like and is a bit more unusual but DH says it sound too much like Myra which is no good at all as it makes him think of Myra Hindley! Interested in your opinions.
