Well, it is difficult, isn't it.
The parish records are very difficult to read - some feint, some missing.
Griffiths Valuation
https://www.failteromhat.com/griffiths/leitrim/carrigallen.htmThere are a couple of McGraths but no Waugh.
The couple are both ‘servants’ on marriage which could mean anything from working on a local estate to a local farmer etc.
However they both offer Carrigallen as birthplace on an English census.
In 1881 there are Rourke and Reilly neighbours - both surnames occur in Carrigallen parish but, of course, they could be from anywhere.
In 1891 there is a boarder, Terence Carney from Carrigallen - again there are Carneys in Griffiths Valuation.
I see one child is Francis Joseph. There is a mention in military records on FindMyPast of Francis Waugh b 1839, Leitrim but I don’t have access.
There is a mention on Ancestry of Francis Waugh, discharge date 1878, Sergeant in 17th Regiment.
He may be in 1881 and later censuses b Gibraltar and living in Salford.
These are likely to have no connection with your Waugh family.
In summary - no sign of them really which is very disappointing.
