John Grow in PA

For the longest time I have been searching for John "Grove/Graff/Groff" born 1797, d. 1860 Georges Valley, Pa
He married 3 times, first wife was Louisa Clinesmith b. 1816, d. 1842.
(2. Mary Gentzel, 3. Elizabeth Stover)
After several dead ends, I searched Louisa and found at familysearch.org a Louisa Clinesmith md. John Grow 1832 Georges Valley.
I am hoping that someone out there may have some insight to this.
I have also listed John's father:
John b. 1775, d. 1809 md. Catherine Stover d. 1845
Any help, greatly apreciated.
