All of us sometimes need to be reminded of things.
For me–it’s spelling a last name consistently when writing about one specific person or couple. In writing a narrative about two members of my Behrens family, I alternated between Behrends and Behrens. I need to choose one spelling.
Documents and records should be transcribed as they are written. But when writing expository paragraphs about an individual, I should use a consistent spelling.
