Leonard and Reuben
Since Leonard/Levi's death was around 1838 or 1839, I am assuming that my own great great grandfather Levi Sheffler is named after him. My Levi was born to Frederick and Catharina Sheffler in 1841, after the death of John and Elizabeth's son just a couple years previous. They also lived in the Sheffler Farm area. (Not only were John and Frederick brothers, their wives Elizabeth and Catharina were sisters.)
Reuben Sheffler (Rubin in the baptism record) died as a 3-month old and is buried in Central Cemetery too.
John and Elizabeth Sheffler, in other Sheffler records relating to New Alexandria PA, are shown as being from Elderton, but they do not appear to have moved there until at least after the 1840 census, as they are living in Hempfield, where these two boys are buried.
