DAACS staff aim to produce a seriation-based chronology for each slave-quarter site using the same methods (see Neiman, Galle, and Wheeler 2003 for technical details). Only assemblages with more than five ceramic sherds are included in these ceramic-based seriations. Since none of the features at the Elizabeth Hemings Site contained more than 5 ceramic sherds, DAACS was unable to produce a seriation-based chronology for the site. However, the site-wide Mean Ceramic Date points to the occupation’s temporal placement at the end of the eighteenth century. The TPQ of 1830 represents a single Bennington/Rockingham sherd from context 1928A1. The TPQp90 of 1775 provides a more robust estimate of the site's TPQ based on the 90th percentile of the beginning manufacturing dates for all the artifacts comprising it.
