One of the specialty publications of The Augustan Society, Inc., was the Plymouth Colony Genealogist, originally titled Plymouth Colony Genealogical Helper.
The Plymouth Colony Genealogist published seven issues between 1974 and 1977, inclusive. They were 8½×11", staple-bound, and ranged from 16 to 32 pages. All are available from the Augustan Society Online Store.
Subject material is now carried in The Augustan Omnibus.
