DATING A TOMBSTONE
One way to figure out the era your ancestor was buried is to examine the
material from which the tombstone is made. If your ancestor has a stone made of slate or common fieldstone (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 your mystery stone is round or pointed soft marble with cursive inscriptions, look for a date of 1845-1868.
Masonic four-sided stones began in 1850 and are still in use today.
Pylons, columns and other exotic-style monuments are usually dated 1860-1900.
Zinc monuments date from 1870-1900.
Granite, now common, came into use about 1900.
If the writing is too faded to read, use a 75 watt black light bulb in
any lamp that casts light directly on the written message. The writing will appear miraculously.
