Name help!

My two and a half year old is named Genevieve Anne after my husbands' mother who passed away in 2004 and shares my middle name Anne. If this one is a boy, it'll be named Joseph William (the J name for my husband Justin and William after my father who passed away in 2002). We know the middle name if it's a girl will be Catherine after my younger sister and for the first name something with an L after my mother, Linda. We've narrowed it down to either Lillian Catherine or Laura Catherine. Which one do you think goes better with Genevieve Anne?
