Freemasons. Commonwealth Lodge No. 409 F. & A.M. (Brooklyn, New York, N.Y.).

Fraternal organizations have existed in New York City as early as 1730, when the first group of Freemasons organized in Manhattan. Generally, these organizations provided social opportunities for members as well as group benefits in the case of death or disability. Organizations attracted members based on religious, ethnic, and national origin. In addition to the Masons, groups such as the Order of the Eastern Star (for female members), Benevolent and Protective Order of Elks (founded in New York City in 1866), and the Ancient Arabic Order of Nobles of the Mystic Shrine (founded in New York City in 1870 by former Masons) were also active in Brooklyn.

The Free and Accepted Masons were by far the most active fraternal organization in New York City and Brooklyn, with over 350 lodges in 1929. However, the Great Depression marked a downturn in membership for fraternal organizations, and by 1990, 186 Masonic lodges remained in the city.
