CROFTHEAD, a village, in the parish of Neilston, Upper ward of the county of Renfrew, f of a mile (W. S. W.) from Neilston; containing 297 inhabitants. This place, which is situated a little east of the road from Irvine to Barrhead, owes its origin to the introduction of the cotton manufacture. In 1792 an extensive spinning and weaving mill was built, around which the village has arisen.
