Brooksby Family Wiki
DNA Studies
Genetic studies linked to surnames are increasingly used in genealogy. The Sorenson Molecular Genealogy Foundation has a description of the methods. On the available databases there is one Brooksby result (as of 09 Nov 2007):
anonymous from the Northamptonshire Branch
Further results from distant male cousins on the Northamptonshire Branch would help to confirm the pattern for that branch and results from other branches would help to overcome the gaps between the branches in the written records.
