Searching for info on 3 brothers: Michael, Richard and Martin Clohosey (born between 1810-1820) who possibly immigrated from the Dunmanway, Cork, Ireland area to the US (perhaps during the potato famine years or a few years before). They came to St Lawrence Co., New York. Any info on their family in Ireland would be greatly appreciated. Know very little about them before coming to the US except that their mother's name was Catherine. They may have entered the US through Canada.
