My great great grandmother was Cecilia Lanigan who was born in Templemore (apparently). She married Thomas O'Brien and had three children Mary b. 1826 Thurles, Thomas jnr. born 1828 Thurles, and Kitty born1830 Thurles. Mary is my great grandmother and she emigrated to Australia on one of the Orphan Ships. She married Andrew Bourke at Portland, Victoria, Australia. I am a descendant of this couple.
The following was quoted in Mary's obituary: "was brought up in Carrickinmuir. She was a daughter of Mr. T. O'Brien, a niece of Dr. J. O'Brien, and a granddaughter of Mr. Lannigan, a barrister, of Templemore."
I think I have found the uncle Dr. J. O'Brien in the United States, however, I cannot find any link to Templemore. I think the Carrickinmuir is meant to be Carrick on Suir??
