Perhaps you should try some spelling variations:
"grey, jan / lady / 1537-1554" » "grew, jan / lady / 1537-1554", "grey, jean / lady / 1537-1554"
"gray, jan / lady / 1537-1554" » "gray, jean / lady / 1537-1554", "ray, jan / lady / 1537-1554"

Try widening your search to All Fields.

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: "((\"grey, jan / lady / 1537-1554\") OR (\"gray, jan / lady / 1537-1554\"))".
• Removing quotes may allow a broader search: (( grey, jan / lady / 1537-1554 ) OR ( gray, jan / lady / 1537-1554 )).
• Adding a wildcard symbol may retrieve word variants: (("grey, jan / lady / 1537-1554") OR ("gray, jan / lady / 1537-1554"))*.
