She is my grandmother and is the daughter of Richard Tullos--She was married to Benjamin Franklin Rigdon and lived in Castor, Louisiana--they had three children--Benjamin ( Buddy) Franklin Rigdon, Jr-- Jesse Dean (Sis)Rigdon and Martha Carolyn Rigdon- I would appreciate any information on my family--thank you so much
