c1900 school photograph of a girl identified on the reverse as Lillian Gay. She was Lillian Auburn Gay of Brockton, Massachusetts, sister of Bertha Wetherell Gay, whose photograph was featured in another post.
The photograph, which measures approximately 2-1/2" by 2", was found with a collection of photographs of youngsters and young adults from Brockton, Massachusetts, and nearby towns, such as Randolph and Braintree.
From brief online research, hopefully correct: [corrections and additions requested]
Lillian Auburn Gay was born January 28, 1891 at Brockton, Massachusetts, the daughter of David Francis Gay and Sarah Clark (Wetherell) Gay. On October 7, 1911 at Brockton, Massachusetts, Lillian married Archibald Frederick Smith, who was born at Easthampton, Massachusetts, the son of John Smith and Sophia (Freitag ?) Smith.
Lillian and Archibald lived at Quincy, Massachusetts, where Archibald worked as a musician. The couple had, I believe, four children. Archibald died in 1966; I don't have a death date for Lillian.
