My Mother's Father by marriage of her Mother (after her birth father died when she was 14) was James Leslie Pettit of Spartanburg SC, born 07/27/1909. He had a sister, Pauline Pettit. There might have been one other sister, but I can't recall. James left his grandparents' Spartanburg farm (sorry, no names known) around 1924, also for the Navy...retiring in 1949. He spent the rest of his life in Norfolk, VA married to Margaret Marie Paul Pettit. He never had children, as his first wife could not bear children and they divorced sometime in the 1950's. He died 04/13/1996.
