Kathy,
I had a look in the tithe applotment records for Tamlaght O’Crilly parish in 1833. There are no McShane farms in Killymuck:

So what that tells us is that the Patrick living there in 1831 was not a farmer. He was most probably an agricultural labourer or some other trade without any significant quantity of land. That seems to be confirmed by Griffiths Valuation (1859) which lists a Patrick McShane in a labourers cottage (plot 23c) on a farm in Killymuck Glebe. (That farm today is up a lane at the junction of the Dunglady and Ampertaine Roads.).

The Valuation revision records show Patrick remaining as tenant of that cottage till 1877 when he is replaced by someone else, suggesting either he had died or moved on by that year. There is a death registered in Ballymomey on 17.11.1873 for a man aged 55. Perhaps that’s 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.
You ask whether someone living in KIllymuck would be buried in Crossmaglen in Co Armagh, or whether someone living in the oen place would work in the other. The short answer is no. That’s about 80 miles away. If Patrick lived all his life in Tamlaght O’Crilly, he’ll be buried there. And if he was a labourer, he is most unlikely to have a gravestone. Most labourers couldn’t afford one. The only exception is where wealthier relatives eg in the USA paid for one to be erected. But most labourers in Ireland in the mid 1800s were buried without a gravestone.
Now having said that, I looked at the civil marriage certificate for Nancy McShane’s marriage to Edward McCann in 1874 in Bellaghy chapel. It shows that she was living in Tamniaran, near Castledawson. That’s in the parish of Ballyscullion and some distance from Killymuck. I also notice her father was described there as a farmer. Are you sure the Killymuck Patrick is the same one as Nancy’s father? (Patrick McShane is a common enough name in the area. I can see 9 people of that name who died around Castledawson between 1864 and 1890).
How do you know that the lady in Tamniaran in 1874 is the daughter of Patrick from Killymuck?
