Photographs of siblings Ethel Gertrude Higgins and younger brother Alfred Lansing Higgins of Cambridge, Massachusetts. They were the children of Frederick A. Higgins and Annie E. (Langille) Higgins.
The reverse of Alfred's photograph mentions Mrs. C. L. Higgins, who was presumably Augusta Hobbs (Lincoln) Higgins of 14 Bay State Avenue in Somerville, Massachusetts. She was the wife of Charles Leander Higgins, the siblings' paternal uncle.
From brief online research, hopefully correct - corrections and additions welcome:
Ethel Gertrude Higgins was born 13 August 1885 at Cambridge, Massachusetts. Alfred Lansing Higgins was born 9 August 1890 at Cambridge, Massachusetts.
I didn't find a record of a marriage for Ethel, but Alfred married Eleanor May Curtis at Watertown, Massachusetts, on 16 September 1916.
Ethel died in 1961 and is buried in the Newton Cemetery at Newton, Massachusetts, with her parents. Alfred is presumably the Alfred L. Higgins buried in the same cemetery, with a death date of 7 November 1962, although that date conflicts with his Social Security death record, which shows January 1963.
