Alexander Graham married in Fermanagh around 1870

At least we know his father's name was also Alexander!

Possible location for Alexander's father - farming at Drumcullion townland in Magheracross civil parish in GV in 1862. It is adjacent to Urbal / Mossfield (in Trory civil parish).

Both townlands just to the east of Enniskillen airport.

Would have been good to find a birth place for Alexander, as we would then know where to look for his family, either in Ireland or Scotland - but the documents don't include place of birth, it seems.  At least we know his father's name was also Alexander!

Have you found Alexander in any census records? if in Ireland should list county of birth but if Scotland should say born Ireland or somewhere in Scotland.

Thank you, aghadowey,
Can't seem to find an 1871 or 1881 Irish census to look at?  Were they destroyed in some way?

The first complete census for Ireland is 1901 (it and 1911 census are online, free) but only a few fragments for earlier ones for a few areas survive.

The original census returns for 1861 and 1871 were destroyed shortly after the censuses were taken. Those for 1881 and 1891 were pulped during the First World War, probably because of the paper shortage.
