Mallett Surname Origins — ‘Mil’ Variants 1851
'Mil' Variations and Frequencies - all Counties

Millett and Millet are the dominant forms of the name. Though there are undoubtedly families who insist on a certain spelling, there is little doubt that both of these names have a common source. Most of the other variations appear to be derivations of the first two, and don't occur in large enough numbers to be considered to be distinct surnames in any event.

'Mil' Variants Distribution by Region

For a listing of the counties contained in each region see “Geographic Regions” on the main 1851 census page.
Given that "Millett" variants are well represented in the West Country counties of Somerset and Cornwall as well as Norfolk, one might reasonably conclude that the name derives from Malet because of the historical presence of that name in these areas, however the name is also very well represented in the Northern Counties where the Malet name has little historical reference and where variations of "Mallett" were not common in 1851.
It is possible that the name is derived from Malet in those areas where Mallett variants are common, and in fact this is quite likely, at least in some cases, but it may also have arisen from other sources elsewhere.
As with all of the other surname variants, the South East region, heavily influenced by Greater London, is well represented by Milletts, but for reasons stated elsewhere, this region should not be considered to be an ancestral base for the name.
