Hi Mags,
There is a Devine living in Ardkeenan still whose father was a Brian Devine. I think there is a connection. My husband grew up in that townland and knows this family. It is about 5 miles from Athlone. The postal address is Ardkeenan, Drum, Athlone, Co. Roscommon. There has been a RC church and graveyard in Drum for centuries. Marriages and baptisms more than likely took place in Drum church. It is part of St. Peter's parish.
Did you get the family in 1911 census (now free online for country)? Can view the actual census form which gives more detail than 1901.
