A student named Minerva Bonner attended the Mordecai school in 1816, both sessions. She's listed as being from Harrisville VA, and has Williamson Bonner as the adult attached to her account. "Minerva" and "Williamson" are nice unusual names, and we have a geographical detail to go on, so this student should be easy to catch in the online genealogical net.
Except... Harrisville VA is in northern Virginia, fairly far from the school's usual catchment area. There are several men named "Williamson Bonner" in Virginia history, but they seem to be from Prince George County and Sussex County, both near Richmond and not in the neighborhood of Harrisville. And I can't find any Minerva Bonners of the right age cohort to work for this student, either.
So, interesting names or no, this entry hits a dead end, unless someone reading this can point me to more information.
