Hi Sinann,
Thanks, I do have that in Mark (Attorney)'s biography.
This was his obituary:
'At Cavan, Mark Magrath. Will refs to Wm, eldest son, daughter Deborah, son James, daughter Jane & husband Richard [Bolton]. Reported 24th Jan 1775 Reported 18th Jan in Saunders.
I have Mark (Attorney), his civic activities in Cavan, his father, quite a lot on siblings and his children. What is new/incognito is this issue of the Inn. He was an attorney from 1726, so what role the Inn had, if this was him, is really what's got me wondering.... He had a brother James and John - James definitely an attorney, John could be.

Presumably that building in Cavan is long gone ....The family were COI and there was a lot going on in Cavan, so I guess if the Inn had a Toll function as per the Balbriggan version, it could have had different uses.
Regards
