HI, friends: Now I'm testing another hypothesis and need help from someone like a Michael Clarke of the early 1800s! I would like to superimpose on top of my OS Sheet # 27 map of Upper Lough Erne a map that shows roughly where the lake level was in about 1811, long before it got drained down. That's when my gr, gr grampa Christopher LYTLE/LITTLE/LYTTLE/LIGHTLE who may have been employed/farmed in the north of county CAVAN was courting his bride-to-be who may have been employed in Crom Estate. In their marriage record of 28 Apr 1812, she was of Aghalurcher Parish, and his folks of Rossorry Parish up by Enniskillen. I suspect it may have been more efficient to commute by boat, than to walk or ride horses. Many thanks again. Doug
