For United States Census Bureau statistics, Guilford is split between the census-designated places of Savage and Columbia.

Charles Alexander Warfield and Elizabeth Ridgley built a joint mill on land patented as "Wincopin Neck".

[13] As the quarry started production again, it was known as one of the best paying jobs for African American laborers, who were not allowed to work in the nearby town of Savage.

A community with two churches and two dozen buildings was formed around the present Guilford and Oakland Mills road intersections.

[15] The First Baptist Church of Guilford was formed by Reverend Willis Carter in a tenant house and has since grown to its fourth new building.

[5] A 1978 survey of the property performed prior to additional development stated that the buildings were in use until the 1950s, but were "demolished long ago" without explanation.

[15] A 2004 survey conducted by the construction firm KCI Technologies contained few specific details of the removal of the historic structures, but concluded that 20 years of continued development "Guilford industrial complex has been extensively compromised by new construction, and, therefore, lacks the integrity required for listing in the National Register" [21] Modern Guilford Road spans from southeastern Columbia, through Savage and Annapolis Junction to Fort Meade.

The road crosses between the most heavily populated sections of the county, reminding residents of a place that is still there, but claimed as part of Savage and marketed as Columbia.

Future plans call for a new elementary school to be built on land adjacent to the Savage Stone Quarry in between Washington Boulevard and Mission Road.
