Bachelors and spinsters are trouble enough to family historians because they don’t add branches to the family tree. On second thought, maybe it’s better that some of them didn’t. In any case, they are also a burden due to the amount of research involved in proving that they never married. Once this is established it would be best to avoid spending more time researching this.

Reunion 9 has a flag (never married) to indicate that this genealogy research is done and the status proved. By the way, you would be wise to include your supporting evidence and the reasoning behind your conclusion in the research notes for the person.
This video from the MacGenealogist Archives will walk you through setting the status flag and the difference between it and the “unmarried” flag.
