Browsing this afternoon I have discovered that there is a Bowthwaite/Bouthwaite in North Yorkshire, so I felt maybe the West Riding is the wrong path to follow. Until, I found an entry for a Poll taken in the West Riding a for knight which mentions Bowthwaite. I seem to remember having read something about a place in North Yorkshire which said it was not to be confused with North Riding. I notice on the map I pulled up Bowthwaite appears to be more West than East. Lefayre.
