Agnes Forsyth Voris was born on December 5, 1844, in Pennsylvania to Gilbert Voris and Catherine Ashenferder. Her father died around 1850. Agnes grew up and attended school in Northumberland, Pennsylvania, and by 1860, her family owned $1,600 of real estate and $400 of personal property. Francis C. Miller began courting her sometime around 1861, and they maintained their correspondence while he served in the Union army from 1861 to 1864. The couple got married in April 1865, and they had at least five children: Hiram, born around 1867; Catherine, born around 1870; Reuben, born around 1871; Anna, born around 1876; and Marian, born around 1878. The couple spent the next few years in Williamsport, Pennsylvania, where Francis worked as a carpenter. By 1870, they owned $4,000 of real estate and $500 of personal property. The family moved to Bay City, Michigan, around 1873, and Agnes’s elderly mother stayed with them for the rest of her life. They moved to Oscoda, Michigan, sometime in the late 1880s, but they returned to Bay City by 1900. Agnes died there of chronic Bright’s disease on December 28, 1905.
