Erith goes well with other strange names people cannot stand. A good dirty trick to plant on your kid as a middle name so they have no choice to go with the more normal of the two. Erith Maynard, Orson Erith, Erith Gladys, Ethel Erith, Erith Gertrude. Not a great array of choices.
Often mis pronounced Edith for people who don't know the difference between an R and a D. Can be pronounced Air-ith but supposed to be pronounced Ear-ith like something to do with your hearing.
Shakespearen: The air-ith smelleth stinkieth in Erith, England.
Erith is Edith with an "r" silly.
When you write a letter to Erith you don't have to say Dear Erith because it sounds funny. You can abbreviate it to "Dearith".
