While searching online for Little Gringley I came across Bassetlaw Museum. Little Gringley and the two market towns of Retford and Worksop are part of the North Nottinghamshire administrative area known as Bassetlaw.
The Welchman Archive of photographic images is well worth browsing.
"The photograph collection contains over 27,000 photographs of the towns and villages of North Nottinghamshire and people who lived there from about 1870 to the present day. 8,000 general photographs from the museum's collections have been added to the Welchman Project images."
I found many photographs of ALLENs, several LITTLEWOODs, plus several references to Little Gringley.
