Owen CASSIDY.[1] Aged 94 at death.

There is a possibility that he had a son that went to the US also named Owen Cassidy.

Y-Chromosome DNA Confirmed
Cassidy-621's direct paternal relationship to Cassidy-1606 is confirmed because:
  1. This yDNA test of Cassidy-453 and this yDNA test of Cassidy-1188 are a close match. 35/37 match
  2. The most recent common ancestor in the yDNA line of Cassidy-453 and the yDNA line of Cassidy-1188 is Cassidy-1606.



  • A Hugh Cassidy was allegedly struck on the head during an argument while returning from a fair in Boho in 1829. Perhaps Owen may also have had a brother or cousin named Hugh? [3]
  • It is not yet confirmed that Owen is the father of William.
  • Whilst I have removed myself as profile manager for this person, it has only been due to watchlist considerations.  Please do not hesitate to contact Veronica Williams should you wish to collaborate on this profile.


Thought to possibly be a brother or cousin of Stephen Cassidy. yDNA results have confirmed a relationship, but now suggests they were more likely to be first or second cousins.

YDNA results Haplogroup I2b1 - origins in Northern France. I- M223.
