I've been to Antietam before but it's been quite some time. I recall the lookout tower and one specific conversation with Dad. At the time, I was particularly intrigued by civil war era bullets. Go figure... Anyhow, Dad was explaining that, if we looked very closely, we just might be able to find one on the grounds.
Wifey and I opted for the convenience of the driving tour that passes through a dozen (or so) historic locations around the battlefield. I'm vaguely aware of our family roots in Washington County. For example, Dad's mom and dad grew up in Boonsboro and Hagerstown respectively.
I was pleasantly surprised to see that one of the tour stops was the Joseph Poffenberger Farm (and house) because my Great Great Grandmother is Fannie Mae Poffinberger (1868-1934). My imagination runs wild thinking about the likelihood of connection between Fannie Mae, her line, and Joseph Poffenberger.
While the J Poffemberger farm is in the best condition and boasts the most information available, there are two other might-be-family-member farms on and around the battlefield. The H Poffenberger farm is located just west of the battlefield and the Line Farm is located just to the southeast.
