Gavin,
Michael & Bridget married 24th July 1892 in Magheralough chapel. Michael’s address then was Glasgow, and Bridget’s Rosnarien, (Rossnareen) near Trillick:

This looks to be your family in Omagh in 1901, though I note Bernard’s place of birth is Tyrone not Glasgow. Evidently a mistake.

1911 census, this time with Bernard born Glasgow.

The 1911 census also tells us that Michael and Bridget had been married 20 years and that they had had 2 children, 1 of whom was still alive.
Griffiths Valuation for 1860 lists Thomas McBrien (Bridget’s father) in Rossnareen. He had plot 1 which was a 10 acre farm.

They look to have been there still in 1951:

The above will should be in PRONI in Belfast. You can view it there free or pay them or a researcher to copy it for you.
The Rossnareen farm today is down a minor road off the Rossnareen Road, south of Trillick.
