Perhaps you should try some spelling variations:
worker volunteer » workers volunteers, words volunteer, brother volunteer
york volunteer » mock volunteers, words volunteer, young volunteer
form volunteer » foot volunteer, from volunteer, forming volunteer
his regiment » his retirement, first regiment, _ regiment

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: 7th new ((((york volunteer) OR (form volunteer))) OR (worker volunteer)) his regiment.
• The words AND, OR and NOT may confuse the search; try adding quotes: "7th new ((((york volunteer) OR (form volunteer))) or (worker volunteer)) his regiment".
• Adding a wildcard symbol may retrieve word variants: 7th new ((((york volunteer) OR (form volunteer))) or (worker volunteer)) his regiment*.
