Torpey in Galway

My great great great grandparents were James and Catherine (Cavenagh) Torpey, married in the parish church in Annaghdown on Dec 18, 1841. Catherine's parents may have been Francis Cavenagh and Ellen Flanagan Cavenagh (or Cavanagh). They emigrated to Philadelphia, Pennsylvania, United States in 1849. I found a marriage record through RootsIreland.ie,and also a Baptismal record for a son, Thomas, onJuly 6, 1843. I am interested in any information about any of these families, especially the Torpeys, particularly a son named John, who would have been born within a year or so of Thomas. Thanks so much to anyone who can help me.
