Sarah Reynolds was born on November 15, 1832, in St. Joseph County, Michigan. Her father, Samuel Reynolds, later came south into this county. The 1882 history places his last years at Union Mills, the village now called Mongo, and Ford has him dying in Springfield Township in 1877 with his wife. None of the four volumes of county history gives her mother a name.
Ford names the Reynolds children: John, Charles, Samuel, Frank, Sarah, Lottie and Mary Jane. Mary Jane married Joseph L. Davis, and Sarah married his brother Hezekiah, on April 10, 1851, by the 1882 and 1920 histories (the 1893 atlas gives 1854). They had seven children.
The marker at Main and Morton says the town's name came from her: Sarah Reynolds Davis named it, honoring a friendly Potawatomi chief. No county history says so.
Whether her name is on the plat depends on the book. The list of original village plats in Ford's 1920 history names two people as filing the plat of January 18, 1889: Hezekiah Davis and Sarah R. Davis. The 1893 atlas, the nearest to the time, says it was recorded by Hezekiah Davis alone, and so does Ford's own chapter on the township. The 1882 history had printed her portrait over her own signature, and listed it in its contents as Davis, Mrs. Hezekiah.
The woman the 1882 book's contents could not name without her husband named the town.
