Hi Monica
I have no idea if they were from that area but I thought it's worth a try.
So far when I have discovered any information about a group with a surname, they have proved to be the same family, though I do realise that will not always be the case. Might even be two groups of the same family.
When you only have names and no place of origin its almost impossible to find people using convential methods. I can only raise the public profile and hope somebody is missing a branch of their tree.
So that's what I am doing, just shaking the tree.
Thanks for your interest.
Regards Allan
