Perhaps you should try some spelling variations:
"william sancroft" » "william moorcroft", "william scott"
"william sandford" » "william langford", "william beckford", "william crawford"
"william smith" » "william sir"
"william scot" » "william scott", "william sir", "william shaw"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("william sancroft") OR ("william sandford"))) OR ((("william scot") OR ("william smith")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"william sancroft\") OR (\"william sandford\"))) or (((\"william scot\") or (\"william smith\"))))".
• Removing quotes may allow a broader search: (((( william sancroft ) OR ( william sandford ))) or ((( william scot ) or ( william smith )))).
• Adding a wildcard symbol may retrieve word variants: (((("william sancroft") OR ("william sandford"))) or ((("william scot") or ("william smith"))))*.
