To me Logan is a boy's name and a surname (like Brooke Logan in "The Bold and the Beutiful"). Personally i find Elizabeth much prettier and more feminine. But unisex names for girls seem to be very trendy now.
I guess the Logan boys suffer more than the Logan girls if they are in the same class. It is ok for a girl to be boyish, but a fate worse than death for a boy to be girlish. This shows that we still live in a misogynic and homophobic society. Sorry for rambling on OT, but this is my pet peeve.
