I have quite a bit of information on the Dillon family. They were a prominent family in the Merlin area (Chatham Ontario) and figured largely in the St PAtrick's Parish.(1855) Most of the family decended from Timothy Dillon (also known as Squire Dillon) He came from County Clare, Ireland and settled on a farm east of the church. He actually donated the land where the church currently stands. His family included Michael Dilon who was a bailiff, Matthew Dillon (occupation?), and James, a broker in Cchatham.
Daughters included Mary (Mrs William Hickey), a Mrs. Dooley and another son Martin who dide in a barnraising accident in 1889.
Timothy dide in 1893 at the age of 85. He also staaaarted the school at the church.,
I looked in my records and see that a Elya Dillon who was married to Wm. Barry were the parents of M. Estella Barry who married Frank GIlhuly on June 21, 1904.
Well that's about it. I hope this helps
