Kevin,
Your posts caught my attention. My great-great grandfather was named Ryland Holman Ford and was married to Johanna Brock. Unfortunately, they seem to be a generation removed from the people you have listed. My Ryland was born 1860 and Johnanna was born in 1861 in Henrico County, VA. It seems to be possible that they are of the same heritage.
Do you have any info on the Ford/Brock lines in this time frame?
