Jacob Granville Richards was born in the 1840's I believe and was married to Elizabeth Virginia Langdon December 26, 1872 in Harrisville, Maryland. Most of the family lived in the Richardsmere Md. area. He was a distant cousin to me by marriage. His son was Granville Hampton Richards who was a doctor and there are several generations in the medical field . I will contact my Richards cousin who is also into genealogy and find more details for you.I believe that Jacob could have also been a doctor but will verify.
