I am trying to track my grandparents ancestral ties to Ireland. I never had the chance to meet them but am curious to know more. I believe one or both of them are from the County Antrim. Their first names were Thomas and Mary. They would have emigrated to the United States in the late 1800's to very early 1900's. I am guessing that they would have come through Ellis Island as they eventually settled in upstate New York (Groveland, NY).
