Hi Claire, I'm researching Seerys, too. My great grandfather was James Seery, he was born in County Westmeath, Ireland in 1843 to Patrick Seery and Catherine Daly. They came over about 1847. Patrick died on the voyage. I don't know for sure where they came into the country, but I think Catherine Seery settled in the Philadelphia area. I think she also had a son named John. James moved to Chicago. Does any of this sound familiar?
