Just saw your post about the Loughreys. The place Clondallan is a townland in the parish of Killgarvan which is in Rathmullan. Co. Donegal. In Griffiths Valuation in 1857 there is a John Loughry living in Clondallan and a number of Loughreys living in the neighbouring townland of Drumhallagh. Today the Loughrey name is still to be found in Drumhallagh.
Hope this of some help.
