Mostly Catherine; some Vacation Pictures
Found grouped together in a wicker suitcase owned by Catherine Cahalan, John C. Cahalan's last surviving child, these photographs are mostly of Catherine, and date from around 1917 to around 1925. After Catherine's death in 1985, the suitcase went to Ann Marie Cahalan, Catherine's nice, and from Ann Marie to my grandfather, Joseph Cahalan, MD.
Many of these images seem to be vacation photos or images taken during a horseback-riding expedition, and feature a very young Catherin, about 18 or so, and friends.
Numbered in the order in which they were originally scanned--a indicates the face, or obverse, of the photo, and b indicates its reverse--the collection includes several photographs in which other figures have been identified; that information is included in the captions to the images. The originals were first grouped and scanned on April 9th, 2008, and have been filed under that date; they were re-scanned at a higher definition for this upload.
