A Helen Crowe who married a Jackson was my cousin. Her dad was Emile Crowe and Estelle Morrison. Emile was born 1878-79. He and his wife had 9 children. Helen was near the youngest. Randolph Crowe was the youngest. That means Helen was born around 1920. This family was born in Hancock County KY.
Helen had 2 sons, not sure if there were other children. One son was named Ray. The other, I only knew by his nick name, "General Jackson".
Probably not the Helen you are looking for, but if it is a possibility, try looking in Hancock County Kentucky records. Helen shot her husband, in the 90's.
