The 1852 Walling map provides a snapshot of the Concord antislavery community in the middle of the nineteenth century.  The inset ("Concord Village") shows the proximity to one another of many of the abolitionist households in town.  Antislavery advocates represented in the inset include Dr. Josiah Bartlett on Lowell Road (just off Monument Square) and Miss Mary Rice nearby on Bedford Street; the Garrisons on Monument Street; the Emersons on the Cambridge Turnpike; and the nexus of abolitionists on or near Main Street from the intersection with Sudbury Road westward—Mary Merrick Brooks at the intersection and Francis and Ann Bigelow just across the street on Sudbury Road; and on Main Street Samuel Hoar and his son Ebenezer Rockwood Hoar, Colonel William Whiting, and the Thoreau family.

The full map (accessible here: http://www.concordlibrary.org/uploads/scollect/BuildingHistories/TownHouse/linkedPages/wallingMap1852Full.html) shows those in outlying parts of town—for example, the Prescotts and Ripleys on Monument Street, the Hunts at Punkatasset Hill (farther up the street), and Abiel Heywood Wheeler on Sudbury Road (at the intersection with Fairhaven Road).  Some prominent Concord antislavery activists—among them the Alcotts, William Stevens Robinson and his wife Harriet, and Frank Sanborn—lived elsewhere when the Walling map was prepared.
