Lt.Col. Mills Stephenson-- Part 2: Masonic Apron

I found some more information about him at the Ohio Memory Collection.

At Fremont, Ohio, there is a Mills Stephenson Masonic Apron which belonged to the colonel.

He is mentioned as one of the builders of Fort Stephenson (now Fremont, Ohio) and was the fort's first commander.

It served as a trading post from 1806 to 1813 and was built on high ground on the western bank of the Sanduskey River,

In the spring of 1813, Stephenson rebuilt the trading post as a military supply fort.  In mid-June 1813, George Croghan took command and became famous for his victory a few weeks later.
