In the Tithes for Monaghan, I have looked for the townland of Derrynahesco (sometimes written Dernahesco) which is on the border between Monaghan, (near Scotstown) and Fermanagh not far from Roslea. I have not been able to find tithe records for this townland. In Griffiths, Derrynahesco is recorded under the Parish of Tednavet, and some maps show it located in the Parish of Clones. However, Derrynahesco does not show up either in the tithes for Tednavet or for Clones! Does anyone know where the tithes for Derrynahesco are to be found? James
