Hi Mike,
Thank you for your message.
Unfortunately it may be difficult to find more information without a more specific place of origin in Offaly. Most Irish record sources- church records, land records, census records- are based on specific locations. Until you know a specific location within Ireland, preferably a parish or placename, it may be difficult to do anything more with these records.
Do you have any documentation-official or unofficial- that mentions any townland, parish, village or town names?
Have you tried looking into his emigration? Generally more information was given at the port of arrival rather than that of departure so it may be a place to find more information-and perhaps even an exact place of origin. For US immigration information check the National Archives at http://www.archives.gov/research/immigration/
Do you know Patrick?s parents? names? If you do you may be able to find them in the land records pertaining to Ireland in the 19th century. Although these do not offer any genealogical information they can sometimes be used to tie a person to a specific place. There are two:
The Tithe Applotment Books (1823-1838) found at http://titheapplotmentbooks.nationalarchives.ie/search/tab/home.jsp
and Griffith?s Valuation (1848-1864) found at http://www.askaboutireland.ie/griffith-valuation/
Have you tried searching Family Search to see if you can find record of Patrick or any of his family? This is a huge database of genealogical records that includes births, baptisms and marriages for up until c. 1880. Unfortunately these collections are not complete but you may be lucky and find either a birth record for Patrick or his parents?? marriage record. You can search this here:

I hope that this is helpful. Remember to post any new information you find, especially a parish name. Remember to post as much information as you can with regard to the people you are researching.
