Greetings, We are seeking any information on the Casson surname in County Laois. A Patrick Casson born in 1812 in Queens County (County Laois) emigrated from Ireland to the United States in 1844. We don't know where in County Laois he was from. He was married to a Johanna Dunn. The name does not sound typically Irish?! We would appreciate any information on the Casson name. Thank you very much!
