Sherman Mills is located in the town of Sherman, in southwestern Aroostook County, near Baxter State Park. Sherman was incorporated in 1862; before incorporation, its name was Golden Ridge.
Researching online, I found that John Clay Spooner was born in Sherman Mills in May of 1895, the son of Thomas W. and Elizabeth (Kellogg) Spooner. Thomas, born in 1858 in Levant, Maine, was the son of Henry and Mary Ann (Beath) Spooner. Henry was born in Kenduskeag, Maine, in 1829, the son of Wing and Abiah B. (Clewley) Spooner. Mary Ann Beath was born abt 1830, probably in Penobscot County, but I couldn't find her parents, and I don't know if Beath is her birth name or married name. Interestingly, Beatham is a common name in Penobscot County, Maine.
John Clay Spooner's mother Elisabeth or Elizabeth was the daughter of John and Lucy Maria (Caldwell) Kellogg. She was born in Island Falls, Maine, in 1866. Her father John was born about 1832 in Maine, the son of Gardner and Elizabeth Green (Foster) Kellogg. Her mother Lucy Maria or Maria Lucy was born in Lincoln, Maine, the daughter of Wesley and Maria Ford (Cushman) Caldwell.
According to the yearbook, John Clay Spooner died from wounds received in the Battle of Thierry on July 25, 1918. An online military reference places his date of death as July 27, 1918. The Battle of Chateau Thierry occurred on July 18, 1918, but I'm not sure of the exact date when he suffered his wounds. It's possible that he's among the 2300 Americans buried in the Belleau Wood Cemetery. The war memorial at Chateau Thierry Hill is considered one of the most beautiful in France.
I don't know if John Clay Spooner married before he went overseas. There's no entry for him in the Maine Marriages online database, but he could have married out of state. He had a brother, Wallace Kellogg Spooner, who also served in the war but luckily survived. Wallace married, had children and died in Lewiston, Maine, in 1962. I hope that he and his grandchildren were a source of comfort to Thomas and Elizabeth Spooner.
