I want to endorse Sheri's request, the first priority has to be a Norfolk Pegg's to tie that group to either Derbyshire or the US cRew, they may be the origin of the US Pegg's.
Fingers crossed, with 4000 Peggs in the UK, that's approx. 2000 potential male tests (the dna must come from a male Pegg) hopefully someone will join in, if you can't do this encourage a male family member to do it. (Unusual Christmas or birthday present)
There are two Pegg results in the public domain which we don't know the origin of, one at Oxford Ancestors another at Sorenson, anyone know the origin of these samples??
The exercise has already thrown up some remarkable results please help with more info...
