Jean,
Finding the McGlone farm is fairly straightforward. Charles & Owen had different farms in the same townland. Griffiths Valuation for 1860 lists his father Charles McGlone in Cornamaddy, on plot 12, a 7 acre farm. Nearby, Owen has plot 6 which is 15 acres of land, but no house. So he presumably had rented it in his own right but was still living in the original family home (plot 12). Plot 12 today is on the Aghafad Rd. Plot 6 is on the Cornamaddy Rd, near Safe Rock Minerals.

Use the slider bar on the Griffiths maps to switch from the contemporary map to a modern day one.
Looking at the Valuation revision records (which take the Griffiths records forward) I see that Charles was replaced by Thomas Carroll in 1867, suggesting he had died. I don’t see a death for him in the statutory records (which start on 1.1.1864), so would guess he died just before that, 1860 – 1863.
In 1870 Owen is recorded as acquiring plot 7 (as well as retaining plot 6). Plot 7 was a house and 7 acres. So he presumably farmed the 2 adjacent plots together. Owen remains tenant of both plots till 1907, then it looks as though Mary replaces him till 1909, after which a Robert Morrison takes over. (The records are quite hard to make out). Griffiths dates were often out by a year or two, as I see Owen died on 10.5.1905 at Cornamaddy, aged 65.

Owen died intestate, but there should be a probate file for him in PRONI in Belfast. Here’s the abstract (brief summary):
Administration of the estate of Owen M'Glone late of Cornamaddy County Tyrone Farmer who died 10 May 1905 granted at Armagh to Mary Anne M'Glone the Widow.
I wouldn’t rely too heavily on Mary Anne’s age in the 1901 census. She was older than 60. Likewise you’ll see that Owen was 66 in the 1901 census but only 65 when he died in 1905. That’s fairly typical, reflecting the fact that most people didn’t really know how old they were and just guessed. As did the informant for a death (in this case his wife Mary). If Mary Ann married in 1853, she wasn’t 12. She’d have been at least 18, so probably born around 1835, or earlier.
The statutory birth records start in 1864 and I see 4 children in them to Owen & Mary Anne: John 12.5.1865; Charles 4.7.1866; Owen 22.1.1871 & Thomas 4.11.1874. For their children born between 1853 and 1863, you’ll need to rely on the church baptism records.
I noticed that another couple in the same area, at the same time, were also having children with the same names. James McGlone, farmer in Crannogue had married Martha Morgan. So I wonder if 2 brothers married 2 sisters? They had a son Owen born 4.11.1875 at Crannogue, but there were other children too.

Can’t help with burial places. Contact the parochial office and ask them for guidance. Cornamaddy appears to be in Pomeroy RC parish:

Tradition was to marry in the bride’s church (assuming they didn’t both attend the same church). So the place of marriage usually tells you where the bride’s family attended, but not necessarily the husband.
