Hi, I have been trying to use what you posted with what little I know to see if we connect.
Martha S. Curtis is in the 1900 listed her birth as Jan 1868 Missouri, She lists her father as having been born in Ohio and her mother Missouri. I cousin I have never met said they had seen her surname written on something as Gay. He was looking for it to email but not yet. She died when her oldest daughter Lula Belle Curtis was about 13. She had 2 brothers and a sister. Her father James Frank Curtis then married Elizabeth "Lizzy" Arnold and had a large family. I have pictures of james Frank and his daughter Lula Belle Curtis. But Lula Belle and her husband Robert A. Powell divorced around 1930. Mom and my Aunt lived with their father and his mother and her second family for several years. The girls lived with her for 2 or 3 years before her death at 36. So first hand info I am lacking!! I have been checking Ancestry for a Martha S. Gay born Jan 1868 MO with no luck. But there are a couple of Martha Gay's born about that time in Ark. So am wondering if she was correct.
