1705-8 has sunk their said shaft grove or pitt for the getting of lead oar, Grinton. As grouas it is found in Yorkshire charters from the late twelfth century but has been translated by editors as ‘pit’. It was employed in the seventeenth century as a name for coal-pits in Colsterdale, where lead was also mined, and subsequently that meaning was in occasional use over a wider area: 1721 I have set forth four workmen of making a New Grove. Examples occur in coal-mining leases in Leeds by the nineteenth century, possibly introduced there via the Danby family who had mining interests in both regions: 1829 liberty to make Pits, Shafts, Trenches and Groves, Leeds.

2) No definition available
‘Grove’ in the sense of a small wood is rare in Yorkshire where ‘grave’ and ‘greave’ are more usual as place-name elements. However, it was used in the eighteenth century when landscape-gardening became popular and emerged as a name for villas in the final decades of the century. Myrtle Grove in Bingley and Spring Grove in Huddersfield helped to establish that tradition. The present-day street directory for Kirklees in west Yorkshire contains over two hundred examples, with no fewer than five Laburnum Groves. It can therefore be compared with ‘lodge’ and ‘grange’, although that aspect of its history has received little attention. Indeed, the rôle these words had as villa names was not commented on in works on place-names, and Smith treated Fell Grove, Spring Grove and The Grove in Dalton as potentially old place-names.
