I did a search of Civil Records at Derry FHC for Margaret (Bellingham) Coulter, with no success. I was searching 1891 to 1901 because she was not recorded in the household with her husband, Hugh Coulter, in the 1901 census, so I assumed she was dead. But, having looked at it again, I see that Hugh said he was “married” rather than widowed. So, maybe she was away overnight on the night of the census.
She was indeed away. She was staying with her son-in-law, David Hunter and his wife, her daughter, Maryetta Coulter Hunter.
