Weeeell....if you want to get geeky, Chewbacca's sister's name is Kallabow and his wife is Mallatobuck.
Of course, there is always Leia
And Leia's and Han's granddaughter is Allana.
Ooooo...there's also Boba Fett's wife (Sintas Vel), daughter (Ailyn Vel) and granddaughter (Mirta Gev)! Boba Fett is my favorite character......
