English:1. habitational name from any of various places named Whitmore, for example in Staffordshire, from Old English hwīt ‘white’ + mōr ‘moor’. 2. Some bearers of the name are descended from John of Whytenmere, Shropshire, who lived in the 13th century. This form is probably a variant of Whittimere, a place on the Staffordshire–Shropshire border, named in Old English most probably as ‘pool associated with someone called Hwīta’.
