Eliza Ann Brighty was born around December 1869 in Bacup, England, to Robert and Eliza Brighty. Her father worked as a “cotton operator,” and her mother worked as a cotton weaver. The family lived in Newchurch, England, until 1874, when they immigrated to America. They settled in Northbridge, Massachusetts, and her father worked in a machine shop there.
Brighty grew up and attended school in Northbridge, and she married Thomas C. Martin on June 29, 1887. They had at least three children: Lillian, born around 1889; Doris, born around 1893; and Caroline, born around 1895. Her husband worked as a house painter in Northbridge. By 1930, they owned a house valued at $3,500. Her husband died in 1938, and she died in Ashland, Massachusetts, on August 22, 1952.
