Evidence key: DOCUMENTED SUPPORTED FAMILY TRADITION HYPOTHESIS DISPROVEN-CORRECTED · what the labels mean · “Potts” = Potts 1883 · “Court Record” = Record of the Courts of Chester County (1910)
One map for the whole family: the Carter land and graveyard, the graves nearby, the British march of September 1777, and where each line went from Chester Township. Use the layer button at the top right to turn layers on and off. Click any pin or arrow to see its name, dates, evidence label and source.
What is on the map
- Carter land, homestead and Carterville sites. The graveyard point is DOCUMENTED. The homestead is shown as an area only, because which surviving house it was is not settled HYPOTHESIS.
- Graves and cemeteries on Concord Road, from the WPA 1936 survey, the county parcel map and Find a Grave.
- Migrations by line. Dated pink arrows from Chester Township, the same routes as the Where they went map. A dashed arrow is a guess HYPOTHESIS.
- The 1777 march and camps, from Brandywine to Aston and on to Paoli. Dashed lines are inferred routes. See 1777.
- Settlements by line. Each family line has its own layer with the towns that Potts names, and each popup links to the people. These points were read by machine from Potts and placed at the town or township centre.
- Historic maps. Four old maps can be laid over today's map. Their placement is approximate.
