I found this
old cabinet card photo on
so many old pictures that turn up at auctions, flea markets or antique
shops, this one has some valuable family information on the back along
with the names of the individuals:
Mrs. R. Chamberlain
Neville Innes Chamberlain
Born Sept. 10, 1875
Robert Innes Chamberlain Born
Feb. 20th, 1882"
was made by the Stereoscopic Company at 54 Cheapside, London, England.
