Pair of Cartes de Visite, or CDVs, of husband and wife John Thomas Lothrop (1844-) and Cora E. (Thompson) Lothrop (abt 1855-1901), taken by the studio of John F. Singhi, 287 Main Street, Rockland, Maine, presumably around the time of their 1876 marriage.
From brief online research, hopefully correct - corrections and additions requested:
John Thomas Lothrop was born at Rockland, Maine, on 16 October 1855, the son of John H. Lothrop and Ursilla (Davis) Lothrop, according to a "Copy of an Old Record of a Birth", with added information from John Thomas Lothrop's daughter Grace May (Lothrop) Winslow Rollins.
Cora E. Thompson was born about 1855 at Rockland, Maine, daughter of William Thompson and Zilpha (Pease) Thompson, as shown on Cora's death record.
John and Cora were married at Rockland, Maine, on 15 June 1876. They had several children, at least one of whom died in infancy. Cora died in 1901. John was mentioned in a City Directory as late as 1935, assuming the correct John T. Lothrop.
