Have you ever heard of the Delany sisters? They were two “colored” (as they preferred to be called) sisters born in North Carolina who both lived to be over 100. They contributed their long life to not marrying:) They were born to a former slave and both grew up fighting racism in their own way. They lived over 100 years together; only living apart a few months. They were both very educated. A book was written about their lives together titled, Having Our Say- The Delany Sister’s First 100 Years (its on Amazon). It has terrific reviews.
