Etymology

Crummock Holme (lost), 1846ValS , Cromackholme 1652 HAS 13, 214, 1748 ib 10, 162, v. holmr 'water-meadow'; the first el. is probably an old Celtic name identical with Crummock Beck Cu 10, from Brit  crumbāco - 'the crooked one', cf. Crumack Close (Bingley) pt. iv, Crummack (Austwick) pt. vi infra ; the particular topographical feature involved here cannot be determined, but the holm was near the R. Ryburn, and Crummack may have been the original name of that river.
