Our 19th Century (Victorian) American ancestors celebrated St. Patrick’s Day in many ways that mirror current / modern observations. The ‘holiday’ has morphed a bit, too, as is to be expected over a 150 to 100 year time span. Many of the 19th century modes of celebration have disappeared and are no longer in vogue.
One of my favorite sources of inspiration is antique photographs. Who were these people? The possibilities seem endless. The images are unlabelled without so much as a year or a photographic studio imprint. That’s where imagination must take over.
