I am a descendant of Ada's sister, Alice Margery Cassidy. Alice married James Achilles. I have gathered quite a bit of information on the Cassady/Cassidy family from Kingsey Falls but I am still searching for their Irish origins. John was born in Ireland according to the 1881 Canadian Census. My mother and I were in Kingsey Falls a couple of years ago and took pictures of quite a few of the Casady/Cassady/Cassidy stones in a cemetery just outside of the town. I would be happy to share the information I have gathered. I am still looking for any additional information I can find. Any assistance would be greatly appreciated.
