I am an administrator with a dna surname project for Mortimer/Mortimore and we now have markers for a number of different branches including two different major branches from Wiltshire, one from Dorset, one from Buckinghamshire and possibly a very large family from Devon. To check to see if you are related to any of these branches you need to be a male Mortimer/Mortimore or have a reasonably close male relative. Please get in touch if you know anyone who is interested.
