Many thanks for your post to the Ireland Reaching Out message board. We have several Carlow volunteers who may be able to assist you. You might also consider creating an Ancestor Profile for Patrick Dunn on the XO Chronicles feature (located at the top of this page). The Ancestor Profiles are widely read and often there are others who are researching the same families as yourself. It can lead to great collaboration and sharing of new information. Please let me know if you have any questions.
