Mary Steen Hill (1849 - 1936) was my 2nd Great Grand Aunt on my Mom's Steen line. I was browsing through online records of the U.S. Post Office at the National Archives online, and came across a document that had her name listed as the Postmaster at Berlin Heights, Ohio. The document was issued by the Post Office Department, and was dated December 18, 1902.
