The National Register listing was expanded by a boundary increase adding 199 Ballard in 1994, and renaming as the Dean Family Farm Historic District.

Dean, shortly thereafter, bought 2,000 acres (8.1 km2) on Caesar's Creek near the settlement of Xenia, but he spent several years litigating to perfect his title.

Once his title was secure, Dean joined Barnes and their families in relocating via Fort Washington (later Cincinnati) to Greene County in September 1812.

They first dined using as a table a huge, flat rock—then began a lucrative business in which Dean harvested and milled timber for lumber used by Barnes to build homes in and near Xenia, Ohio.

At least 36 of his 111 progeny enlisted and served honorably in the Union Army during the Civil War, according to records read at an 1880 Dean family picnic.
