In 1901 there was a change to the land holdings John Conneely was now holding 4 Acres 1 Rood 2 Perches while Patrick Hussey held 3 Acres 3 Roods and 5 Perches rather than 6 Acres 1 rood betweeen them. The rent remained the same.
In 1940 Patrick Hussey changed to Thomas Hussey

A local genealogy publication called The Cloonfad Magazine is published each December. The site is currently down for upgrading works. If you write to The Committee of the Cloonfad Magazine, C/o Cloonfad Post Office, Ballyhaunis, Co. Mayo. and give them the above information they should be able to come back to you with an update on Sonny Mitchell.
Note Cloonfad Cemetery has a plot with a steel cross with the name Patrick Hussey.
I hope the above is of assistance to your research.
Martin.
