1. 01

   Identify material

4. 04

   Use local dates

   Complete this step before moving on. For how to date a gravestone by material, record the evidence that changed your confidence rather than only the final conclusion.

Use several dating signals

Material, tool marks, lettering, construction, maker signature and cemetery chronology should agree before assigning a date range. Replacement markers and reused family plots can deliberately mix periods.

Start with observation

Write down only what is physically visible before assigning meaning: shape, orientation, count, material, damage, text and relationship to the rest of the monument.

Add context

Use the inscription, date, cemetery section, neighboring family stones, local religious history and records. Context can strengthen an identification or show that a familiar-looking motif was used differently.

Record uncertainty

A useful research note separates observation, interpretation and evidence. Mark what is documented, what is probable and what remains only a possibility.

Preserve the site

Do not move objects, apply substances, make rubbings, clean, reset or repair a marker without permission and appropriate conservation knowledge.

A reproducible note is the goal

What slate, sandstone, marble, granite, bronze and cast zinc can—and cannot—tell you. The best result is not the most dramatic interpretation; it is a conclusion another researcher can test from your photographs, transcription, context and linked references.
