Use Headstones as a Resource
1. A headstone is a physical piece of evidence that they really lived.
2. They provide birth and death dates.
3. They can be a means of discovering other family members. I've found many spouses of ancestors by finding a headstone.
4. On occasion, their epitaphs reveal a little bit about them, whether it's an occupation or how they died, etc.
