ROHAN OR ROUGHAN

[Aussie_trekkie]

I am searching for Thomas born late 1700 or early 1800 . I am visiting Ireland and have been to Nenagh where I met Rohan's. They told me they are from Michael who was from Killaloe or Ogonnelloe in Co Clare. He opened a pub in Nenagh in 1857 they were not able to help with Thomas but suggested I try Ogonnelloe. I drove through it last night and I would like to call back but I was hoping someone may have information or can direct me where to search . The areas that keep popping up are in Clare around the Ballina and Killaloe . Thomas had a son Patrick born in 1830/31. I have searched the main church in Nenagh but no sign of Patrick who was born in Tipperary according to the census 1871 Liverpool. No sign of Thomas here too. Any suggestions ?
