I found this photograph attached to a family tree at ancestry.ca, and contacted the owner for permission to post at my site. The owner kindly granted my request.
This is John Killeen, son of Denis Killeen and Mary Ahern:
John Killeen was born about 1828 in March Township, Carleton Co., Ontario.
On 20 December 1852, he married Margaret Fahey, daughter of John Fahey and Margaret Lahey. I believe he was the first in his family to marry a Lahey, but he certainly wasn’t the last. On 12 January 1858, John Killeen’s youngest sister Margaret Jane Killeen married John Lahey, son of James Lahey and Ann Armstrong, and first cousin of Margaret Fahey. And in the next generation, John James Lahey, son of John Lahey and Margaret Jane Killeen, married his cousin Bridget Loretto Killeen, daughter of Patrick Killeen and Bridget Galligan. Said Patrick was also a son of Denis Killeen and Mary Ahern, and therefore a brother of John Killeen and of Margaret Jane Killeen. Confusing? Yes. You really need visual aids to figure out the Killeen-Lahey connections.
And then there are the Galligan connections. As mentioned above, Patrick Killeen, son of Denis Killeen and Mary Ahern, married Bridget Galligan (1835-1861), daughter of Patrick Galligan and Mary Cullen. Meanwhile Denis Benjamin Killeen, son of John Killeen and Margaret Fahey, married Bridget Galligan (1858-1938), daughter of John Galligan and Ellen McGee, and a cousin of Patrick Killeen’s wife Bridget Galligan.
John Killeen and Margaret Fahey lived first in March Township and then in Torbolton Township, Carleton Co., Ontario, where they raised a family of ten known children, at least four of whom emigrated to Minnesota. Margaret Fahey died on 5 November 1899; and John Killeen died on 6 November 1906. They are buried at St. Isidore Roman Catholic Cemetery in Kanata (formerly March Township).
