A more thorough explanation:

SINE PROLE

Sine prole is a Latin phrase that means "without issue." It was commonly used in genealogical tables to indicate that a person had no children or descendants.

The abbreviation for sine prole is s.p.

1. John Smith (1800-1850) married Mary Johnson (1805-1880) but died sine prole.

2. Elizabeth Jones (1900-1950) had two children, but both died young. She died sine prole.

These examples show that the individuals mentioned did not have any children or descendants. The use of sine prole in genealogical tables helps to clarify family relationships and inheritance rights.
