Grow family of Chester County, PA 1800s

I am looking for any information on Rachel E. Grow who was the second wife of Capt. John W. Ford 1840-1919.Rachel was either married once before Capt. Ford or had a daughter, Lillian Grow 1869-1940, out of wedlock. Rachel and Capt. Ford lived in Chester County, PA and had three children together: Manning F. ford 1881-1955, Reynold M. Ford 1883-1949, and Alice N. Ford Rissel 1886-1957. Rachel died sometime around 1890, but I haven't been able to find here grave. I don't know who Rachel's parents were and I don't know who Lillian's father was either.Any help would be greatly appreciated.
