My Grandmother was Illa Myrtle Cox Harrell. Her Mother was Stella King. She married my great grandfather Frank Cox. I have found the death certificate of Stella Cox, However I am not sure of her mothers name on the death certificate. It is believed to be Mathas Wilson. I can not find any such info on Mathas. I think Maybe her name was Martha. I have came to a deadend in looking past Stellas family. I know that Stellas mother and father both are from person county nc. ANY info would be a big help.
