That sounds a likely reason for the name of the field; great that it's used and the name lives on! This picture of an OS map from 1937 shows a sports ground and pavilion on this site. It also marks three stones - picking up from the earlier post and the 1892-1914 map. Think these photos show two of them and what's left of one of them (along with bonus lambs). The markers in the same field have 'SH' inscribed in them.
