From the IGI portion of Family Search, we learn that Henry Buck was born in Lycoming County, Pennsylvania on March 1, 1778. He married Jane Corson in 1810. Hewson L. Peeke wrote in A STANDARD HISTORY OF ERIE COUNTY, OHIO, that Henry Buck was one of the earliest settlers of Erie County, and he died of cholera in 1849. His date of death was September 9, 1849. Henry Buck is buried in Sandusky's Oakland Cemetery.
Not all the words in the inscription of the tombstone of Henry Buck are legible. Here are the words I could decipher:
Remember man as
...by for as thou
...prepare to die
And follow me.
This may be a variation of the tombstone inscription found in an 1848 issue of the New England Historical and Genealogical Register, available at Google Books:
