My Great-Grandmother Bridget Cassidy was born in Monaghan in1830. She was convicted of stealing a quilt from her employer and was transported to Australia in1848. Her father was listed as John Cassidy but no record of her mothers name has been found. Any descendant of Bridget or anyone having any further information on her I would be grateful to hear from you

My 7th great grandfather is from Cavan, Ireland. I am a surgeon and my father was also a physician. Came naturally and now I know why!

Butch Cassidy was not a Cassidy! Robert LeRoy Parker (April 13, 1866 – November 7, 1908), better known as Butch Cassidy, was a U.S. train robber and bank robber, and the leader of a gang of criminal outlaws known as the "Wild Bunch" in the American Old West.


Butch Cassidy and the Sundance kid. Famous American story but Butch had grand parents who immigrated if I’m not mistaken.
