One way to figure out the the year your ancestor was buried is to examine the material from which the tombstone was made.
If your ancestor has a stone made of slate or field stone (except wood used by pioneer) chances are the stone dates from 1796-1830.
If the stone is flat topped hard marble, dates are about 1830-1849.
If it is round or pointed soft marble with cursive inscriptions, look for a date of 1845-1868.
Pylons and column monuments are usually dated 1860-1900.
Zinc monuments date from 1870-1900.
Masonic four-sided stones began in 1850 and are still in use today.
Granite, now common, came into use about 1900.
