“Smithsons & Relatives” (1981) https://media.geni.com/p14/67/2d/c2/e0/534448621334a6df/joel_terrell_original.pdf?hash=b798f2ac579182270020a3721df47093bc6f99eb99791577044f4104fefcc903.1670745599
On Page 333, it covers the Chiles & Terrell families, and there are differences from the main source used for Geni:
Tidewater Virginia Families p235; chapter#9: The Chiles Family (also Peatross Ancestors) on ancestry.com with image < AncestrySharing >
Geni shows this Ann, daughter of Joel, married to MANOAH Chiles:
Ann Elizabeth Chiles & Manoah Chiles
