Take the M4 from Dublin and move to the M6 near Kinnegad.
Leave the motorway at the exit for Tyrrellspass traveling towards Mullingar. Leaving Tyrrellspass to your left take the turn to your right about 2 miles down the Mullingar road.Roughly 1 hour
It has Meedin indicated. Its a narrow road but you will find Meedin Church and Cemetary.
If you continue on the road after visiting the Cemetary you will pass a farm house on your right This family may be able to help. Other than that travel on to Rochfortbridge taking the left turn on to main road after a small hamlet called Gneevebawn . I think there are Hyland famililies in the general area of Farthingstown and Rahinquill both only a few miles apart and near Gneevbawn
