I am responding to this post that I just seen today. I just made the same statement you made about African Americans with the last name Cassidy. My last name is Cassidy and I am African American.In fact my Name is David William Michael Cassidy, my father was David William, and his father was William Earl Cassidy. As far as the hotel in New Orleans, this is the first I have heard of it. I just met another African American whose name is Michael David Cassidy and his father is named Michael David Cassidy. he is the only other Cassidy of African American heritage outside of m family that I know. I would love for you to look at are family tree and see what you can find. You may contact me at n4davesart@verizon.net. I would love to hear from you or the other African American Cassidys you are connected to.
