Samuel Hardin Grant with wife Sarah Margaret Rooks

Early photo taken of my Great Granmother and Great Grandfather. she is holding my grandmother Pearl Grant White, the little boy was Alfred, he died shortly after the picture was made. I am looking for any information on the Grants or the Rooks family. This picture was taken in Kentucky..possibly Adair or Casey County. Please contact with any info.
People in photo include: Sarah M Rooks and Samuel H Grant
