Mosley

English (chiefly southern Yorkshire and Lancashire): habitational name from any of several places called Mos(e)ley in central, western, and northwestern England. The obvious derivation is from Old English mos ‘peat bog’ + lēah ‘woodland clearing’, but the one in southern Birmingham (Museleie in Domesday Book) had as its first element Old English mūs ‘mouse’, while one in Staffordshire (Molesleie in Domesday Book) had the genitive case of the Old English byname Moll.
