Martha is in my wife's direct line. Various traditions exist about the school, often just called the Durham School.

One tradition claimed Martha used money from her divorce (first marriage) to build the school building and teach there. Another tradition claims the building was there before Martha's short stint there.

Either way, Martha only taught there for a short time before she and her husband emigrated from Jackson County to Greensburg in Decatur County, Indiana. She died in Greensburg in 1926.

I'd be interesting in comparing notes with you. Please contact me via email.
