Last I heard Ireland and the UK are not Schengen members. Another option for an inmate wishing to spend a lot of time in the Schengen Area, could be to get a passport from a country that's a Schengen member. Some European countries allow citizens of other countries who are descended from a citizen of that European country to obtain dual citizenship, and hence a passport from that country. Italy is one such, and I believe Ireland is another. There are hoops to jump through, of course and plenty of criteria one must meet. In the case of Italy, for example, my recollection is that you have to present proof that your qualifying ancestor was an Italian citizen, which usually means hiring a genealogist in Italy to track the info down and prepare a report. And even after you have all your proofs and paperwork submitted, it can take a year or longer to find out if your application has been accepted. There are numerous websites devoted to this topic.
