John never wrote about Fitzgerald Thanksgivings in any of his book series. One can assume nothing exciting happened. I doubt it.
In 1905, Papa, Thomas Fitzgerald oversaw the town turkey shoot. Eastern Utah Advocate recorded the following.
A few years later the Advocate printed the results of the 8th grade Thanksgiving Fundraising Ball. (Yes, that is John’s oldest sister, Isabelle, highlighted in the top paragraph. She and his brother William had nearly perfect attendance at school).
Religious worship topped the scale. Two separate columns announce the annual Methodist Thanksgiving Service “for everyone.” I imagine the Fitzgerald’s attended these. Though they weren’t Methodist, Papa and Mamma, in book and real life were highly supportive of the various faiths in their community.
