I was wondering if there is any history at all of Manus Gallagher owning a flower business in the 50's in Philadelphia, Pennsylvania.
We do not have membership records from that time period.
We do not have any Flower show programs from that time period. The ones we have digitized begin in the year 1966.
You can search these programs yourself
We’ve also digitized our year books that you can search online. You can search through the ones from the 1950s.
(you'll need to open the year book up in Internet Archive and search inside the volume).
Hope this helps. Good luck with your research. You might try contacting the Historical Society of Pennsylvania. They deal with lots of genealogical questions.
