This is the tombstone of Louis F. And Cora (Roop) Schumm, located in row 8 of Zion Lutheran Cemetery, Schumm, Van Wert County, Ohio. The marker is inscribed:
April 5, 1913
Ludwig Friedrich “Louis“ Schumm was born 4 March 1892, the son of “River“ Henry and Magdalena “Lena“ (Geisler) Schumm. Louis was baptized at home on 20 March 1892, with Ludwig Schumm and Friedrich Kreiselmeyer serving as his sponsors. His sponsor Ludwig Schumm was his uncle and was also my great-grandfather.
Louis‘ father was known as River Henry because he lived near the St. Marys River and to differentiate him from several other Henry Schumms living in the area at that time.
Louis Schumm grew up in a large family. His father River Henry (1844-1922) was married twice and Louis was the oldest of the three children from his father’s second marriage. Louis grew up with two full siblings and eight step-siblings.
The children from River Henry’s first marriage to Anna “Rosina“ Schinnerer (1854-1890):
John Martin Schumm (1873-1954), married Lizzie Boroff
Clara Rosina Schumm (1875-1936), married Ernest George Dietrich
Minnie Schumm (1877-1958), married Martin H. Hofmann
Hannah Barbara Schumm (1878-1937), married George Merkle
Edward Ludwig Schumm (1880-1885)
Gustavus Jacob Schumm (1881-1951), married Dorathea Elizabeth Bienz
William Jacob Schumm (1883-1967), married Marie Sauer
Tillie Sarah Mathilda Schumm (1886-1971), married Ernest Theodore Merkle
Joseph Henry Schumm (1888-1957), married Edith May Smear
Carl Friedrich Schumm (1890-1893)
River Henry Schumm‘s first wife Rosina died in 1890 and the next year he married Lena Geisler (1868-1946). They had 3 children:
Louis Fredrick (1892-1974), married Cora Roop
Herman Andrew (1893-1984), married Anna Goellner
Theodore Gottlieb (1898-1967), married Leona Stetler
The River Henry Schumm family in 1910, living in Willshire Township: Henry, 65; Lena, 42, wife; Louis F, 18, son; Herman, 16, son; and Theodore, 11, son. 
Louis Schumm married Cora Eva Roop on 5 April 1913 at the Zion Lutheran parsonage at Schumm. They were married by Zion’s pastor, Rev. George J. Meyer. The church records note that both were from Willshire. Lillian E. Meyer, the minister’s wife, was the witness to their marriage.
Cora Eva Roop was born in Van Wert County 18 March 1884, the daughter of Jacob Lewis and Mary T. (Strickler) Roop.
The Jacob L. Roop family in 1900: Jacob, 55; Mary, 44, wife; Albert, 20, son; Cora, 16, daughter; and Lizza, 11, daughter. Cora attended school and her father Jacob was a farmer in Willshire Township.

Louis Schumm was one of the best carpenters and home builders around. In fact, Louis Schumm and Bill Baker built my parents’ home in 1957. Bill Baker, who was also a very good carpenter, learned from the best. I also remember Louis and Cora’s daughter Mary Schumm, who was a very talented musician. She played the harp and organ and probably even more instruments. She was my first organ teacher, back in the early 1960s. I learned a few years ago that Mary had also been a close school friend of my Aunt Ruth (Miller).
