Leitrim -- Cassidy, John+Bridget=Patrick+Mary Ann+John

[nskaug]

Searching for info abt John Cassidy (1850/Leitrim) and his son Patrick (1874/Leitrim). The family moved to Lancashire around 1880. Patrick (My g-grandfather) later emigrated to Trinidad (West Indies) where he married. Also need tips on websites where official records are easily obtainable. Thanks from Norway.
