I have a hard time thinking of names until I know the gender. Once we get those results (around 5 months?) we'll go to the family trees and pick something old. Lulu's named after my greatgrandma.
We actually have the name of the first woman and man in our family to come to America (in the 1600's): Isabella and Petrus (as in Peter). Then the names get really funky : Temprence, Joziah and later, Hildegaard!
My husband actually is suggesting naming the baby (if she's a girl) after our Newfoundland dog who died this spring. She was an important member of our family -- the spark, the glue, believe it or not. But I just can't see doing that. My dog has such a singular part of my memory and heart, it would be confusing to have a child named after her. You know? Still, I thought my husband was sweet for suggesting it.
(Hey, we would have an LL Bean monogrammed dog bed for the baby all ready down in the basement!! )
