Naming characters can be a pretty grueling process. Or for some folks, the names jump out at them. Either way, please for the love of God don’t use too many names that are too similar or all start with the same letter. It makes reading more difficult for the reader because in print, the words start blurring together.
For example, in Lynsay Sands’ novel Bliss (which inspired this post), the hero is Hethe, Lord of Holden aka “The Hammer” (it really takes an effort not to hear Wrestlemania when I see that name). Our heroine is Helen. They are ordered by King Henry to marry to stop their quarreling. Adding to the melee is Helen’s Aunt Nell, whom she is named after. Looking at the names repeat over and over again gave me a headache, and while I liked the story I felt like I had to put in extra effort to keep the characters straight.
On paper, they look like the same person. It’s hard to tell them apart because of the way people read:
