All I know is that Joseph had a sister Jane Cook. Groves seems to be perhaps their mother's name. Jane was sentenced during the famine to transportation to Australia in 1849 and said she had a brother Joseph Cook in Philadelphia. She was born in Co. Tyrone c.1824. That's really all I know about him but I am trying to find their town/village of origin. I know its a long shot and maybe impossible through him but I thought I'd see. thanks, Lyn
