There are several minor French places with this name. In England the name was used in particular to denote a fortified manor occupied by a landlord. The surname may also have been an occupational name for someone who was employed in such a manor.
2. From a Norman female personal name composed of Magin- strength, might and Hild - battle.
This entry (from the Oxford Dictionary of Surnames) suggests that the name should be widespread if not more common than it is. Most entries are derived from two landed gentry families in Yorkshire and Derbyshire.

Minne - occurs infrequently in IGI93. Not sure of pronunciation but almost certainly it is Minney, many entries found in Belgium (and in modern telephone directories). I have found one reference in Michigan USA 19thc who at various times used spellings Minne, Minene, Minnie and Mini (see NorthWest Kent FH journal March 1990). Also appears as the ancestral name for Minnie in South Africa.
Minnee - found in Holland, believed to be from Protestants fleeing France in 17thc. May also explain Minnie found in South Africa.

Minney - a variant derived from Mennell/Minnell found in parish registers of Long Buckby and Yardley Hastings, Northants occurring from 1600 to 1700 before finalising on Minney. One theory for the change from Minnell to Minney is that in Old French the stress was on the last syllable; Minn-ELL. When the surname became anglicised the stress moved to the first syllable; MINN-ell, at this point the surname became more English in pronunciation; MINNel. Since this would have made little sense and the 'll' is a weak sound easily lost, the alternative Minney grew up. The loss of the 'll' is more easily understood if the name holder moved, was illiterate, misheard by a clergyman who did not understand the dialect etc.
Minnich - German for monk
Minnie - as a South African surname. Derived as a nickname for Minnar from Mesnard (from Old French for inhabitant of a small house) according to one source but more likely to have come from Holland e.g.; Minnee.
