Hey there!
I don't know how commom the name Kulba is, but my Mom's maiden name is Kulba. I'm 17 years old and like you, trying to research my ancestors. My mom and aunt names: Jenny Kulba and Jocelyn Kulba. My grandfather: Stephen William Kulba Jr. My grandfather's sister: Carolyn Kulba. My grandfather's father: Stephen William Kulba Sr. My grandfather's mother: Frances Connors. My grandfather's Aunt: Jennie Kulba. My grandfather's grandfather: Wasyl (aka William) Kulba. My grandfather's grandmother: Ann Bodnar.My grandfather's Great Grandfather: Daniel Kulba. My grandfather's Great Grandmother: Victoria Kulba. Apparently Wasyl Kulba came here from the Ukraine. Don't know if this links me to you in any way, but I thought I would share. Good Luck!
