Looking for the Dunfees & Conestains

Looking for any information on James Dunfee, born 1842 in Kilkenny. He married Catherine Conestain (or a variation of this name), born 11 Feb 1840 (based on 1901 & 1911 Canada Census) in Ireland- though death notice says 1834. He was Catholic. He moved to Port Hope, Ontario around 1881 where he was a Labourer. It appears Catherine may have moved to Ontario earlier but this is not clear as one census says 1845 & another 1860. Her father's name was Misshel; mother Mary White. I have no information on either of her parents. His parents were Luke Dunphy/Dunfee & Mary Walsh.

What I have on James:

Bn Co. Kilkenny '42; em '52. H/o Catherine Coanstain. F/o Jas. & Mrs. Jas. Cashen. Also 4/4(obit).

A notice in the 06 Mar 1896 Port Hope Weekly Guide states:

James Dunfee, the subject of this notice, was born in the County of Kilkenny, Ireland, 25 Dec 1842. He came to Canada as a boy at the age of 10, with his parents, and has been in Port Hope for 44 years and in the employment of Mr Beamish for over 40 years. He worked in the plaster mill (where he was milling grain) until 12 o’clock Tuesday night and went to bed after partaking of a cup of coffee, and before 1 o’clock next morning he fell into that sleep which knows no waking. He was of a most retiring disposition, and everyone had a good word to say about Mr. Dunfee.. All of the farmers in this part of the country knew and respected him. In addition to his aged widow, he leaves one son, Mr James Dunfee, grocer, and one daughter, Mrs James Cashen, of Coburg, who is now with her mother. The funeral took place on Sunday afternoon, to St. Mary’s Cemetery.

Any leads would be most appreciated. thanks, Marcia
