Mary Ann seems to have led an uneventful life as far as information in the public record is concerned. She was born in Poona on 4th September 1837. When her elder brother William Samuel Price III retired from the Indian Civil Service and moved to Guernsey, she moved there as well. At the 1891 census she was living with her brother and his family at the Manor House. By the time of the 1901 census she lived in her own house and apparently had her own means of financial support. Her address was The Matiaes, Village de Putiou.
Mary Ann Price never married and died in Toronto on the 12th April 1923. (Her niece, Mary Ellen Price, had confirmed that she died in Toronto in the 1920s.)
