The Horn family emigrated from Hesse-Darmstadt in the Bundesland (federal state) of Hesse in Germany, which is located in the southern part of the Rhine Main Area. LDS microfilm archives.
John Horn (1796 – 1870) was born in Hesse-Darmstadt, Germany to Heinrich Jozef von Horn. According to his immigration papers, John came directly to Maryland where he established a farm in Jarrettsville, Marshall District. Three sons and his wife Elizabeth Treusch (1784-1849) most likely followed him once he had a place for them to live. The sons were William (1820-1880), Adam (1823-1885), and Henry Joseph (1831-1917).
Arriving at the Port of Baltimore from Germany on September 30, 1834 was a Horn family. I don’t know if this is the same Horn family, but it is the same year noted in the naturalization papers.

On April 7, 1849 John Horn signed a deed for a 48 acre piece of property, known as “Plaine’s and Bell’s Habitation” over to Adam Horn for $600. On June 13 of the same year, Adam Horn and his wife Charlotte deeded 3/4 of an acre over to the church trustees, Jacob Gross and John Gross) of the Evangelical Association for $5.00. The stated purpose was to build a church on it. More about the lives of these early German settlers in Jarrettsville can be found in Forgotten Churches, The Evangelical Association in Harford County, MD. pages 24-37. www.lycoming.edu/umarch/chronicles/2001/4.%20Salem%20Church.pdf
According to the same source, Henry and Ellen Horn (she was the daughter of aforementioned trustee Jacob Gross and his wife Catherine Burger) also deeded land on April 18, 1865 for the church parsonage. However, the land they deeded to the church was ultimately not used for that purpose. The parsonage was later built on another piece of land. In 1877, the land that Henry & Ellen Horn had signed over was sold by the church to a private individual with first option to Henry Horn if the new owner ever wanted to sell it.
The census records prior to 1850 only list head of household. But from 1850 on they include the family members and anyone else lodging in the household.

The headstone states William was born 29 March 1820 and died 1 May 1895. Maybe it was erected at a later date and no one was quite sure, since the 1880 Census Mortality Schedule shows him as having died in 1880.
