David Gilbert (20 Aug 1850 - 14 Jan 1937)
According to records, Gilbert was a photographer from about 1880 to 1932.
In 1933 David and wife Anna are found in Columbus, Ohio, and he is working as a clerk. He is 82.
His death certificate mentions he suffered from “senile dementia” for four or five years before his death in 1937.
Since no other information is available at present, the cards at left must have been done between 1880 and 1932.
