Hi Marg,
Thank you for your message. Unfortunately it may be difficult to find further information due to John?s early birth and transportation date.
Here is a link to Armagh Ancestry which shows what records are available online, as you can for Seagoe church records do not start until circa. 1830?s.

I did do a quick search for Darragh in Griffith?s Valuation and there was on result for Darragh in Seagoe:
http://www.askaboutireland.ie/griffith-valuation/index.xml?action=doNameSearch&Submit.x=28&Submit.y=9&Submit=Submit&familyname=darragh&firstname=&baronyname=&countyname=ARMAGH&unionname=&parishname=
I wonder if this was one of John?s other sons?
Here are some websites that you may find useful, hopefully you can find some more references to the Darragh?s through one of these:
