Grady and Hanlon families of Aghaboe

Trying to trace the family of a Martin Gready or Grady , and his sister Margaret.Martin was born abt 1816, and was transported to NSW around 1834/5. He was transported with his brother in law William Hanlon. William married Margaret Grady in Aghaboe on 1 Jan 1831. We would like to,find out if the Grady's were actually from Aghaboe or the marriage was held there because possibly the Hanlons were local. Also wondering if this area is far from Roscrea? We are thinking this Martin Grady and Margaret may just possibly be from Roscrea. Can anyone help with these queries?
