The residences on an Irish marriage certificate are where the couple were living at the time of the marriage. It is not where they were born (though they might have been - but a person’s birthplace is not recorded on Irish marriage certificates). The fathers might also live at those addresses but again that’s not recorded. You cannot assume that the fathers were alive. They could be dead. Occasionally Ministers and priests put “deceased” against a father’s name but mostly they didn’t bother.
In this particular case there is a Samuel Acheson listed in Kinkit in Griffiths Valuation, so that looks likely to be your family. In 1858 he had plot 2 which was a 31 acre farm. A Robert Acheson was living in a labourers cottage on the farm so likely to be a relation.
The Valuation revision records show that farm remaining in Samuel’s name till 1876 when it changes to Thomas Atcheson. That suggests Samuel had died. There’s a death for a Samuel Atcheson regd in Strabane on 19.7.1875 aged 88. That might be him. You can view the original certificate on-line on the GRONI website, using the “search registrations” option:
You will need to open an account and buy some credits. It costs £2.50 (sterling) to a view a certificate.
Thomas’s name remains as tenant of the farm till around 1909 when he is replaced by Thomas Keys. However Thomas isn’t in the 1901 census, so what happened to him is a bit unclear.
The Robert Atcheson in the cottage died in 1883 aged 70. Here’s his death certificate:
Here’s the death of another Samuel Atchison of Kinkit born c 1842, in 1890. He’ll be related to the family but it’s not immediately clear how:
This looks like his widow:
Daughter Marys’ birth certificate tells me her mother was Sarah Ann Loughlin:
Family in 1911:
Marriage for one of Robert Acheson’s daughters in 1873:
A Samuel Atcheson of Kinkit married Mary Ann Todd in 1853:
They could be the parents of the Mary Acheson who married Wm Robinson. You would likely need to search Urney Church of Ireland baptism records to confirm that. They start in 1813. There’s a copy in PRONI in Belfast.
