The village of Dalmatia in Northumberland County is situated along the Susquehanna River, on land once owned by William Dunbar, an early settler who purchased the property from Thomas McKee in 1773. One enduring mystery of Dalmatia is how this inland village came to be named after a coastal region of Croatia, as early records indicate that no one of Croatian descent has ever lived there.

Another mystery involves the strange deaths of three young children in the home of Charles and Ora Matilda Zeigler. After Ora took her own life by setting her home on fire and shooting herself in 1931, it was whispered that she had murdered her grandchildren with poison, for reasons that are just as mysterious as the name of the village where the triple tragedy occurred.
