I've been looking through my Stottlemyer files to answer your inquiry regarding Sarah F. Stotlemyer Trail.I do have one possible match: a Sarah Stottlemyer born about 1842 in (West) Virginia, daughter of Peter and Jane Stottlemyer.This Sarah was the second daughter of 10 children.
A note in my file shows "He (Peter) may have moved to Allegany, Maryland in 1842 or 1843 from Virginia.This is indicated by the birth places of his children as shown in the 1850 census."
The father of this Sarah is Peter Stottlemyer b. 1806 in (West) Virginia, and died in 1876 in Washington Co., Maryland. He was married to a woman named Jane, of whom I have no other information. My files show Peter was the youngest son of David Stottlemyer Jr. b. abt 1766 in Middletown, Frederick Co., Maryland, d. 1 Feb 1821; and Margaret Agnes Magruder, b. abt 1768 in Wolfsville, Frederick Co., Maryland, d. abt 1826 in Wolfsville, MD.David Jr. and Margaret were married in March 1791 in Middletown, MD. David Jr. was the fourth son of David Stadelmayer>Stottlemyer, who immigrated from Germany in 1750.
I can do more checking if you have any more information about Sarah F. such as a death date and place, siblings, or other relatives.
