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

Mallett is clearly the most dominant form of the name, followed by Mallet. Together they comprise 92% of all the 'Mal' variations found. Though there are families that use one variation or the other in modern times, we know from our research that these top two names are more or less interchangeable in the historical record, and as can be seen on the Surname Variant Distribution Map that follows, in the most populous ‘Mallett’ areas, large numbers of ‘Mallets’ are found too. In any event, given that the difference between the two spellings is very slight, there is no reason to consider them to be from distinct sources.
Much of the variation seen here might be attributable to census enumerators' interpretation of the spoken word. None of the other variations occur in large enough numbers to be considered to be distinct surnames either - they all appear to be variations on the same name.

'Mal' Variants Overall Distribution
Each symbol on the map represents at least one occurrence of the associated name in a particular location - but does not accurately represent population density.

'Mal' Variants Distribution by Region

For a listing of the counties contained in each region see "Geographic Regions" on the main 1851 census page.
It is fairly obvious, looking at this table and the following two maps, that the Mallet/Mallett surname is most prevalent in the West Country, East Anglia, and the Channel Islands. Given that the Malet surname can be traced historically to these 3 areas in the 11th and 12th centuries, it is reasonable to assume that the name derives from these early Malets.
By the same token, since the Mallet/Mallett name does not seem to have any large base in any of the Northern Counties, then perhaps we can conclude that the surname variations found there (primarily Millett), are not derivatives of Malet, and must have an independent source.
As with all of the other surname variants, the South East region,heavily influenced by Greater London, is well represented by Malletts, but for reasons stated elsewhere, this region should not be considered to be an ancestral base for the name.
'Mal' Variants Population Density by County
