We spent one day with John in Dublin. All four of us wished we had more time with him. Not only does he know the history and context of various sites but he is fascinating to just talk with about current events. The pre-planning advice he offered was simple and effective so we got spots to see the most popular sites. He took us to a great pub for lunch and his vehicle was very comfortable. John knows ancestry and was able to talk at some length about our families likely heritage and he gave us some great tips for more investigation of the family tree.
