Name gender?

Lynsey
Not that it matters a lot, because I'm not changing my mind at this point, but I'm wondering: if you met someone who said they were having a baby named Lachlan what would you assume the gender of that baby is?
I went to tour a child care facility today, and the woman showing the facility said "wow, what is beautiful name!" Then looked at me with a little guilt and said, "but I have to ask, are you expecting a boy or a girl?"
(Sorry if you're Scottish or Australian - I know this is a popular or normal name there... it just isn't in the United States!)
