Harriet Lane

de bene esse: literally, of well-being, morally acceptable but subject to future validation or exception

 

Although she was the niece of bachelor President James Buchanan and not his wife, Harriet Lane was nevertheless considered the First Lady of the Buchanan White House, according to Firstladies.org. But, similar to other benevolent wives of our presidents, Harriet committed herself to two underserved populations that needed help -- Native Americans and children.
