If you think the Eisenbrey Cliff below is interesting....

Here is a photo of the original Deed dated 24 August 1785 for the property that John Isenbright (Eisenbrey) bought from Michael Taylor and his wife. The property was at 7th and Sassafras (now call Race Street) Sts., in Philadephia. The location of the property is today (2014) the Philadelphia City Police Headquarters. The property was passed at Catherine Eisenbrey's death to their son, John and was purchased by William Eisenbrey in the 1850s. Denise Eisenbrey Snow now has the original deed in the family archives.

Below is a stereoview from the 1860s which shows the Eisenbrey Cliffs at the Delaware Water Gap in Pennsylvania. This site was trailed by W. Harrison Eisenbrey and the cliff view was named after him. More information about this to come:
