Maria “Mary” Margaretha Müller was born 4 June 1800 in Rittershausen, Districts Unterfranken and Aschaffenburg, in the Kingdom of Bavaria. She was the daughter of Conrad and Dorothy Müller and Zion Chatt’s records also indicate that she was baptized and confirmed in Rittershausen.
Mary Müller married Erasmus Stump in Bavaria, probably about the year 1828. Note that Stump was sometimes spelled Stumpf in the church records. Erasmus and Mary had three children, Phillip, Catherine, and Gertrude:
Philipp Stump (1829-1917), married Barbara (Geisler) Adam, the widow of Heinrich Adam
Catharina Stump (1830-1902), married August Albers
Gertraud Stump (1832-1846)
Erasmus Stump died in 1838, likely in Bavaria. Later that year his widow Mary (Müller) married John Hiller. John was the son of Johann and Margaretha Hiller, who was born Kingdom of Bavaria in 1805.
The next year, 1839, Johann and Maria Hiller and Mary’s three children from her first marriage immigrated to America. This information was included in Zion Chatt’s records as well as on a passenger arrival card. On the passenger card Johann Hiller was 34 years of age, born in Germany about 1805, and is shown traveling with Margaretha [Mary], Philip, Catharina, and Gertraud. John’s occupation was a weaver and their destination was the U.S. 
After their arrival in America the Hillers resided in Butler County, Ohio, for eight years. In about 1847 they moved to Adams County, Indiana, and settled a few miles from Chattanooga, where they attended Zion Lutheran Church.
John and Mary (Müller) Hiller had the following two sons, who were both born in Hamilton, Butler County, Ohio:
Jacob (1842-1926), married Martha Sundmacher
Johann “George” (1846-1932), married Caroline Brecheisen; married Catharine Alt
In 1850 the Hillers lived in Jefferson Township, Adams County, Indiana. In their household: John Hiller, 48, a weaver; Margaret, 45; Jacob, 8; and George, 4. 
In 1860 the family had a New Corydon, Indiana, post office address and John farmed. In the household: John, 54, Bavaria; Margaret, 60, Bavaria; Jacob, 16, Indiana; George, 15, Indiana. 
John Hiller died 10 March 1869. After his death his widow Mary lived with their son Jacob and his wife Martha (Sundmacher). Their farm had a New Corydon Post Office and enumerated in the household in 1870: Jacob, 28; Martha, 24; George, 1; John 10/12; George 24; and Margaret [Mary], 69, born in Bavaria. Living next door was Mary’s son from her first marriage, Philip Stump and his family.
