Hi Elle,
I am tryin to trace the irish side of my family, my grandfather was Charles Doherty, and his father was John Doherty who married a woman by the name of Catherine Burke, according to my aunty this was his second marriage. They had two children, Charles and Mary, there was mention of another child, Kitty who i think died from TB. Not sure if any of this rings any bells with you, but if it does please get in touch, we may be able to help each other out!
