Kelly and Elly doll 1970's (not sure on name)

I am trying to find a baby doll mid to late 70's. She has blond pigtails and a flannel blue jammies. She also had a toy elephant with her. I thought her name was "Kelly and Elly" or "Kellie and Ellie", but I haven't had any luck finding anything like it.

Anyone that knows the right name or where I could find her, please leave a message! Thnx
