McPhillips on Tedavnet Parish 1800

Recently through DNA I have come to think that my Thomas McPhillips and his wife, Margaret Sullivan came from Tedavnet parish in Monaghan. They were somehow blood relations to either; Deery, Murray, McKenna, or Sherry surnames as that is where the DNA has put the connection. (Those DNA surnames came from Tedavnet.)

Thomas Sr. was born about 1800. Thomas Jr. was b. 6 Jan 1834. Two daughters were Sarah, b. abt. 1835 and Catherine, b. 15 Feb 1837.

Since I don't know they arrival date I'm not sure if they came through Canada or from New York, USA to Wisconsin, USA. Later, they moved to Nebraska, USA. Margaret died at sea on the trip to America

. Looking at the townlands where the DNA surnames lived and those same townlands that McPHILLIPS lived in according to Griffth's and the New Graveyard of Tedavnet, the possiblity seems evident. But which Townland that Thomas & his wife and children lived in and left is a mystery. Any help with my Great grandparents story would be appreciated. Dona
