Etymology
Latin hērēs names the person entitled to inherit. The same ancestor underlies heredity, connecting legal inheritance of property with the passing of traits from parents to offspring.
In context
the husband died first. And statistically, given the dangers of warfare, accidents, and occupational hazards, he often did. The wife needed support. But the husband's heir, usually his son, also had legitimate claims to the property
