My father grew up on this farm north of Lebanon in the early 20th century.

Part of the Swartz farm.

Agreed. It was also part of the Schwartz property when I was growing up in Lebanon in the 60s and 70s. However, my grandfather, Elbert Snider, owned this 80-acre farm from 1904 through his passing in 1940. I have a 1932 plat book of Warren County that includes this area. The Stratton farm was to the south, and long-time Lebanon teacher Lucile Berry owned property to the north of the Schwartz's.
