Just in case back in 1829-1832
http://titheapplotmentbooks.nationalarchives.ie/search/tab/results.jsp?surname=owens&firstname=&county=Monaghan&townland=&parish=&search=Search&sort=&pageSize=&pager.offset=40Among 45 Owens I just note two for your thoughts. the first because it’s the only Clones based Owens
Owens James Melgins Clones Monaghan 1832 when I looked this up I couldn’t find any Owens at ref 1944 there is a James Rep which could mean James Owens has died and he had 1 acre. if so and he a very young son, that person Michael could have been brought up elsewhere and if not happy with home of famines might have emigrate later, or allowed to stay with his mum etc etc
Owens Mich Carnaveagh Aghnamullen Monaghan 1829 The entry when looked up shows the area of each farm
1. Hugh Jackson 40 acres
2. Jos h Cunninhham 39 acres
3. John Owens 3 acres
4. Michael Owens 2 acres
5. Thomas Owens 4 +acres
Notes 2 acres wouldn’t support a family so he could be a farm labourer to 1 or 2.
Notes Aghnamullen civil parish is SSE of Clones travelling through Kileevan , Aghabog, and Ematris SSE of Clones notes Clones is also part of Dartree something Each have Owens living at this time.
Notes there are Owens listed in Kileevan, [Killeevan], Aghabog, and Ematris
Hoping something new for you Good luck onwards BallyaltikilliganG
