Gravestone inscriptions provide birth and death information and offer family relationship clues. The only record of an immigrant's original surname may appear on that person's headstone. However, as secondary sources, gravestone inscriptions can contain errors. Genealogical and historical societies and various individuals have transcribed and published cemetery inscriptions.

Tombstone decorations offer insight into the deceased's economic status, occupation, religious affiliation, interests, and organizational memberships.
