Another Killeen couple with surprisingly few marriages amongst their offspring:
Bridget Killeen was one of the daughters (possibly the fourth daughter, and fifth child) of Denis Killeen and Mary Ahearn, and a sister of Hanora (married Michael Donahue), and also of Ellen (married Mathew Daley), of Patrick (married Bridget Galligan), of Margaret Jane (married John Lahey), of John (married Margaret Fahey), and of five other known siblings. She was born at March township about 1827, and died at Maniwaki, Gatineau Co., Québec in 1910.
On 2 May 1854 (Notre Dame, Bytown), Bridget Killeen married Patrick Cavanaugh, son of Christopher Cavanaugh and Jane Malone, and an emigrant from Co. Kildare, Ireland. The couple lived in March township, Carleton Co., Ontario for the next six to eight years, where they had five known children (Mary Jane; Margaret; John Christopher; William; and Anna Esther), before moving to Maniwaki, where they had another three known children (James Patrick; Denis Joseph; and Albert). Patrick Cavanaugh was a blacksmith, as were his sons John, William, and James, according to the 1881 census (Quebec, Ottawa, Egan and Maniwaki, household of Patrick Kavanagh, family no. 15; LAC; click thumbnail to see larger image):
