Looking for passenger list on Patrick & Sabina (Carney) Kearns, who apparently escaped the Irish famine and came to North America. They had two sons with them Thomas and Michael. We believe they arrived in 1846 as Mary Ann, according to family lore and census records, was born either off the coast of Canada aboard ship or just after the family arrived. Not sure which port. I've searched New Brunswick ports and through ancestry.ca to no avail. Can anyone help?
