Laffredo, Loffreda, Loffredo, Lofredo

Background

The Loffredo Surname Project aims to reveal more about the history of all Loffredos through sharing of information and DNA testing.

Families started using Loffredo as a surname in Southern Italy in the Naples area, but it has since spread around the world. Some sources claim the name is of Germanic origin but this is not yet proved.

The part of DNA which is passed from father to son to grandson, etc., is known as Y-DNA, and changes very little from one generation to the next. This enables us to compare the Y-DNA of males and to see how closely related they are, so it is an ideal tool to enhance any knowledge gained from our paper trails. As Y-DNA is only passed between males, female Loffredos cannot take the test themselves. However, they can still participate if they find a father, brother, uncle, etc., willing to take the test on their behalf.

Several versions of the Y-DNA test can be taken, namely the Y-DNA12, Y-DNA25, Y-DNA37, Y-DNA67 and Y-DNA111 tests. The difference between them is the amount of Y-DNA which is tested, with the Y-DNA12 test being the most basic and the Y-DNA111 being the most comprehensive. The Y-DNA12 & Y-DNA25 tests are not really recommended as they are not accurate enough to be confident of matches found. The Y-DNA37 test is the bare minimum that should really be considered, but the more markers tested the better, so the best test to take, if possible, is the Y-DNA111 test.

Once members receive their initial results they will also be assigned to a Haplogroup (a branch of the human tree). Further tests can usually then be taken to give a more detailed Haplogroup assignment. For an introduction to European Haplogroups please refer to:-
