The earliest known PB assembly was Coonville Gospel Hall that met in Coonville, Dearborn Heights, Detroit, Wayne, Michigan from 1901-1904, and was an open brethren meeting.

Dearborn Heights Christian Assembly was founded in Detroit in 1927 as a Grant exclusive assembly, and split between 1933-1936, with one group becoming an open brethren assembly known today as Dearborn Chapel, and a remaining Grant-Booth assembly that likely joined with the KLC's in 1972, and folded sometime after 1977. See Who's Who at Dearborn Chapel, MI for an alumni list of both assemblies, with regard to anyone on the list from 1933 or before.
