While sharing some other Masonic finds with family, my grandmother revealed to me that her father and grandfather were members of the fraternity as well!
I emailed the Grand Lodge of Ohio seeking some additional information and was able to obtain the following:
William E. Cowin:
Member of Hillman Lodge #481 changed their name to Wick Lodge #481. They are still an active lodge in Poland, Ohio. This is all the info I could find on William. The Shrine office had a storage issue awhile back and were unable to locate his record for me.Darlene Shirk – Grand Lodge of Ohio Genealogy
Robert J. Cowin:
Received his degrees in Tuscan #342 – left there and joined Andover #506. Tuscan was located in Pierpont, Ohio and has since merged with Relief Lodge #284. Andover has since merged with Triandria #780 in Rock Creek, Ohio. The Grand Commandry Recorder reports that Robert was an active member of St. John’s Commandery #20, Knights Templar of Youngstown until his death.Darlene Shirk- Grand Lodge of Ohio Genealogy
