Thank you very much for your query to Ireland Reaching Out. You are fortunate in that Patrick/Peter left so many clues behind him. Have you check the General Register Office (GRO) for his birth record? You should find additional information about him, such as his parents names, etc.
Also try the land record called Griffith's Valuation (1848-64). When you find out his parents names, then you can consult this for information about where they lived.
There could be records about the construction of the Middlesborough Opera House in Middlesborough. Consult any available records, as these could give information such place of origin, age, pay, maybe even where he trained.
Best of luck in your research!
