Jim,
It appears this is your family in Gortnacorkoge in both census,1901+ 1911.
There are a number of families of the same name in various townlands around the village of Drumkeerin & others a little further out in Killargue.
The family was mostly Methodist or Church of Ireland religion,but those in Gortnacorkoge & a couple of others were Roman Catholic.
On checking the Irish Telephone Directory,there is no one of the name now listed in the area.
There are some listed in the neighbouring counties of Roscommon & Sligo.
There is a Genealogy Site which covers that area & all of North Leitrim.It is
Drumkeerinfolk@yahoogroups.com.
It is f.o.c. only requisite is that your ancestors come from this area.
