About us

The Dalton International DNA Project is one of the largest and most respected projects of its type internationally and has many sets of DNA markers in its database. We still need to expand it further, particularly with individuals who have documented ancestral lines that take them back to known British or Irish Dalton origins. The strength of the database as a family history research tool lies in its size, and its continued growth is of paramount importance to us all.

We have over 300 registered participants in the project and well over 80% are members of one of the 15 identified genetic families.


So, if you are a Dalton male and you have yet to take the plunge, please do think about joining this well-established and exciting project. If you wish to participate, please contact Karen Dalton Preston the Project Administrator, and we will be pleased to discuss what is involved in more detail. Or, if you have already had your DNA tested, please consider joing our private Facebook Group D*lton Surname DNA and Genealogy.

Mark Wholihan, our DNA consultant, is available to answer any questions on the Private Facebook Group. You can review prior DIDP Reports here or on the appropriate link below. Mark is planning a revised Report by the end of 2020.

We host a private Dalton DNA Group on Facebook and a Dalton Surname GEDMatch group (registration required for both services).

A summary of our current position:

The DIDP DNA project is growing from strength to strength year on year. Our goal this year is to recruit more Daltons in order to build up a comprehensive and more accurate genetic picture of British and Irish Dalton trees.

This is a long-term task that we cannot avoid working on in order to develop the project, but each and every one will greatly contribute to clarifying the overall picture and answering the big question:   'How many Dalton families are there?'
