Belated happy new year greetings all. Yes, Tom, there is mention of Cassidys in the book. 18 persons mentioned in the index of persons and 13 references to the surname. The author Fr. Peadar Livingstone, had some of his students (including one of my brothers) count the occurances of all Fermanagh surnames in the 1962 electoral register. The book contains a table of the 100 most common surnames and Cassidy was 13th overall and 5th of the old gaelic names native to Fermanagh. Although the book was first published by the Clogher (diocese) Historical Society in 1969, the currently available reprint (1990) is published by Hall's bookshop; (L.W.N. Hall, 32 Darling Street, Ennislillen, Co Fermanagh.) an excellent local bookshop always with something new on local history. I have no connextion with the bookshop (except that I cannot pass without entering when I am in Enniskillen). Unfortunately not on line so far as I am aware. Maurice Cassidy
