I'm trying to get a Mallett (and variants) Surname DNA Study up and running.There are 600+ such projects for various surnames already in progress.It involves doing an analysis of the Y-chromosome, carried by all males, that is passed from father to son (along with the surname) with, usually, no change.
There are known mutation rates for the Y-chromosome though, that allow one family to differentiate itself from another over time.This type of DNA testing is a very useful tool that allows one person to determine if they are related to another or not, even though they may be separated by several degrees of kinship.
Most of the Mallett/Mallette etc. family genealogies that I’ve seen, whether from the USA, Canada, or Australia/New Zealand, trace their descent from an ancestor who came from either France or England.The Malet surname was known to exist in Normandy, France prior to 1066, and in the eastern part of England shortly after that date when William Malet accompanied William, Duke of Normandy, in his conquest of England, and was subsequently given large estates located primarily in Norfolk and Suffolk. About 100 years later the name also shows up in the Western part of England, in Somerset.
The main goal of the project, then, is to prove (or disprove) the following premise:
All Mallett/Mallette (and other variants) families stem from a single ancestor in Normandy, France, who took the surname circa 1000 AD.
A second, very useful, aspect of the study that will emerge over time will be to identify different family groups within the main group. This is accomplished by taking the DNA test results and marrying them to known genealogies.For instance, one family group’s genetic pattern (haplotype) will indicate that their most recent common ancestor (MRCA) came from England, not France, and even a particular region within England.
Once the various family branches have identified haplotypes, then someone who has hit a brick wall earlier in their research can participate in our study, discover that their haplotype matches one of the established haplotypes, and realize that they should focus their future research on that branch.
