Need help with a middle name

We already have a daughter and we won't be finding out the sex this time around. We have picked a boys name we like; Maverick John Chechalk. But can't think of a middle name for our girls name. Our first daughter has both our mothers middle name(Lynne) so we don't have another family name to use as I don't have a middle name aswell as any other women in my family! So I need help lol! First name will be Charlee and last name is Chechalk!
