My work is exploratory, with much more to do. My emphasis is history and culture. I am trying to develop a picture of who the Wexford Codds are, their lives, etc in the contexts of period. This won't duplicate the One-Name-Study or DNA project, but there are areas of mutual interest. I like to consider a variety of sources - traditions, documented material, images, artifacts etc.
It is not always possible to establish connections. I think in terms of possibilities, highest probability, what supports a particular case or weighs against it.
Getting some dialogue going on the Wexford Codds would be great and could add a great deal more insight.
If you know a direct male descendant of a Wexford Codd willing to have their DNA studied, Joe Flood may be keen to hear from them.
