Henry Erben
1846

Identified through online information from T. Daniel Hancock. -- The New York City Organ Project website reports "In 1846, St. Mark's-in-the-Bouwerie asked Erben to rebuild the 1824 Hall & Erben organ, but Erben refused, charging that the organ was actually built by Hall and was of inferior construction. Instead, Erben built a new two-manual organ for the church." This organ seems to have been replaced by a 3/30 Henry Erben in 1854; or perhaps it was enlarged.
