Could it be that Richard went to Ireland to see or work with his brother,Oliver, who was Lord Deputy and other offices of Ireland.
It doesn't mean that he, necessarily stayed there or that his children were there. I don't understand any distress the people in Wales feel. The people I talked to in Purley Magna and Bletsoe were very sympathetic and helpful.
If thews people have any information about Richard and any possible family I would certainly like to hear it.
