Did you know Dottye Robertson / Moore?

Ok so here goes! I am looking for anyone who may have know my mother named Dottye Robertson / Moore. She passed away in a car accident in 1973. I have an older sister who was raised by Dottye until she was 5 years old, when Dottye passed away. We also have an older brother out there who was born in Arizona 1963 - 1965 (?) Yes we are looking for him as well. We'd like to find out more about our mom and maybe we can find some more photos of her as well. And maybe we might be able to find my birth father as well! Again her name was Dottye Robertson / Moore. She died while living in Columbus Ohio. Thanks for helping or at least reading my post and best of luck in your own search efforts!
