Jonas Fuller was born around 1843 in Pennsylvania to Ransom and Abigail Fuller. His father was a farmer who owned $1,300 of real estate and $627 of personal property by 1860. The family lived in Springhill, Pennsylvania, until the 1850s, when they moved to Wyalusing, Pennsylvania.
Fuller enlisted in the Union army on August 7, 1862, and he mustered in as a private in Company A of the 141st Pennsylvania Infantry on August 18. He died of “Congestive Fever” in Leesburg, Virginia, on November 2, 1862. A comrade assured his parents that Fuller did not die alone: “He died in my arms and as I closed his eyes, I felt that I had lost a friend and brother.” After Fuller’s death, his friend noted, a “lady from a house opposite plucked some nice flowers roses & formed them into a bouquet and brought them over to lay on the breast of the dead Soldier.”
