I have no idea who these people are. Mother and father appear to be prosperous, their daughters plump and well-dressed. Could they be the circa-1900 equivalent of today’s upper-class brownstone Brooklyn family?
The portrait studio is located at 494 Fulton Street. Today, this is part of the Fulton Street Mall, but a century ago, Fulton Street was lined with opulent department stores (Abraham & Strauss, Loeser’s) and fancy restaurants (Gage & Tollner).
Perhaps this family lived nearby in fashionable Fort Greene or Brooklyn Heights. Maybe they had their own brownstone—one that is now home to another young Brooklyn family.
