Matrilineal Monday: Where Grandma Minnie and Cousin Margaret Got Married

In 1911, my maternal grandma, Hermina Farkas married my grandpa, Theodore Schwartz, at the 8-10 Clinton Street Synagogue on the Lower East Side of Manhattan.

Here's their marriage cert. Note the name of the top witness: Marcus Aronoff.

This same gentleman witnessed the marriage of Grandma Minnie's first cousin Margaret to husband Herman in 1913, at the same synagogue, with the same rabbi officiating.

How does Marcus Aronoff relate to the family? Or was he a head of the congregation or some other official in the synagogue?

UPDATE: Cousin L noticed a very important detail: My Grandma Minnie lived at 745 E. 6th Street when she married, the same building where his mom (cousin Margaret) lived when she was married by the same rabbi in the same synagogue, just 18 months later. Here's a street view of that building, a 6-story apartment building built in 1900 that still stands today. Yet another indication that the families were close!
