Here’s what the Online Etymology Dictionary has to share:
"a slattern, woman of the lower classes," c.1275, from fem. proper name Malkyn, a dim. of Mault "Maud" (see Matilda). Also attested from c.1207 as the proper name of a female specter. Sense of "untidy woman" led to meaning "mop, bundle of rags on a stick" (used to clean ovens, artillery pieces, etc.), c.1400. Attested as the name of a cat since 1673; used in Scotland and northern England as the name of a hare (1724).
As for the word Matilda:
fem. proper name, from Fr. Mathilde, of Gmc. origin, lit. "mighty in battle," cf. O.H.G. Mahthilda, from mahti "might, power" + hildi "battle."
Interesting. Wikipedia points out a few unlucky souls whose last names are Malkin, like political blogger Michelle Malkin. Not that there’s anything wrong with it, but I know I wouldn’t want that to be my last name. ;)
