Welcome to the Adamthwaite Archive, where you can access a range of resources to help you research your Adamthwaite ancestors - the information on the site has been made available through the generosity of members of the Adamthwaite mailing list on - together we are trying to link up all the branches of the family that are spread across the world, and to share the information that we have  uncovered in our own research.  


You might like to start your journey of discovery by reading about how our Adamthwaite One-name study began, or learn more about One-name Studies in general.


For information on how to use the details on this site and about the colour coding system used to identify the ten different family lines reconstructed to date, please read this explanatory page first.  To navigate around the site, just click on the section links above, or take a look at the Table of Contents to see what type of information is included in each of the sections.


There is also a whole section on the History of the Adamthwaites.


If you have Adamthwaites in YOUR ancestry and you want to discover where they fit in our ten lines, in the first instance, search the Master Name Index.  If you have any difficulty finding them, please use the Contact Form to tell me their names, approximate dates, and place of residence of the most distant Adamthwaite (and their spouse!)  I will be delighted to help you work out where you belong.




If your surname is Adamthwaite, or if one of your ancestors was an Adamthwaite, please get in touch using the Contact Form and tell us how you are connected - I shall get back to you very soon.  And who knows, you might have information that could solve a genealogical puzzle!


Can you help to further our knowledge about the origins of the Adamthwaites by participating in our DNA project at Family Tree DNA?  Please read the project information and contact me if you would like to help in any way.  If you have already taken a DNA test with a different company, find out how you can transfer your results to our project absolutely free.

We still have two FREE yDNA test kits available for male Adamthwaite volunteers: see here to find out if you qualify for one of them.
