The book, Ulsterheart, an Ancient Irish Habitation was published in 1989 by All-Ireland Heritage, Virginia USA, 0962154407 ; OCLC number 22378274
Ulsterheart is an intensely personal documentary of nineteenth century life in the parish of Errigle Kerog, County Tyrone ("Kerog" is the spelling preferred by Rev. Ingram, the author, as noted by his daughter, Gladys Perrier), mentioning many specific people and their contributions to the economy and culture of the community. Families and relationships are recounted, giving thE book a strong appeal for those who trace ancestry to this county in what is now Northern Ireland. Especially useful in this context is an alphabetized index to all Church of Ireland baptisms from 1812 to 1832, in Chapter 5.
The book is a full history of the area, from earliest archaeology to the early 20th century. In “The Ulsterheart” we have the culmination of a lifelong interest in Local History and in the Ballygawley district in particular where he spent more than half his adult life as Rector of its group of three parishes. The author, who was born in Dublin of Sligo parents was always a countryman. He was at home here in the centre or heart of Ulster where he ministered for 27 years in the ancient parish of Errigle Kerog (Argel Kerog) since his appointment in 1960.
