Hi tjj. Glad you enjoyed the review. I've tried to find mention of Dernavogy near Aughnacliffe, but the only mention in any of the maps is a Dernavogy Road in Co. Fermanagh near Fivemiletown. Then I ran a regular find and this came up: https://www.daft.ie/price-register/longford/aughnacliffe/dernavogy/ Interesting. Maybe that was your family's place.
