Thank your reply. I have considered that the DNA connection could be through another ancestor and have looked closely at this matches extensive and we researched tree- far bigger than mine. No surnames seem to be in common with my own, however, well at least so far. Counties,yes. We have those in common but otherwise only the surname FitzGerald. Funnily enough I have another small one yesterday when searching through unviewed matches. Not as well researched a tree, though.
smaller marches are hard to work with! On Ancestry however I have several 6cm verified matches! Someone in New Zealand has done lots of work on our Wilson tree!! All well documented.
You me tion repositories- what are they? Guess they are only accessible in Dublin??
