I have very limited access to Irish records - as I state I'm happy to help with English research - but Pockradge Dancy came from Ireland. His census returns state that.
There are 27 entries for him though in Ancestry trees (just counting the entries in public trees) and I dont know whether you have made contaact but one tree has his parents as a Richard Dancy of Dublin who married a Mary Foster.
(There seems to be one born in Cavan Ireland abt 1810 and one born abt 1812 in Armargh Ireland)
there are also websites with information about Pockrage/Pockridge Dancy (although you have probably seen these already):www.dancy.net/culage/danceyp.htmwww.dancy.net/culage/dancyp.htm
Sorry I couldn't be of much help
