Perhaps you should try some spelling variations:
"william kingston d.d" » "william kynaston d.d", "william kidston d.d", "william livingston d.d", "william kingston dec", "william kingston david", "william kingston dans"
"william kingdon d.d" » "william langdon d.d", "william king d.d", "william condon d.d", "william kingdom d.g"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"william kingdon d.d\") OR (\"william kingston d.d\"))".
• Removing quotes may allow a broader search: (( william kingdon d.d ) OR ( william kingston d.d )).
• Adding a wildcard symbol may retrieve word variants: (("william kingdon d.d") OR ("william kingston d.d"))*.
