In "The Possibility of Evil" by Shirley Jackson, is Miss Strangeworth's name ironic?

I don't think Miss Strangeworth's name is intended to be ironic. Rather, it seems intended to characterize her as a strange woman who has a lot of dignity and high moral standards. I can't help feeling that the author's choice of the name was a mistake. For one thing, it doesn't sound like anybody's real name, does it? Besides that, it forewarns the reader that this old lady is a little bit crazy, doesn't it? The reader shouldn't be forewarned but surprised when the nice little old lady sits down and begins writing her poison-pen letters. In my humble opinion, a simple name would have been better because it would not have made Miss Strangeworth stand out among the other townspeople.
William Faulkner chose the fairly simple name of Emily Grierson for the main character in his short story "A Rose for Emily" because he didn't want to dilute the shock that comes at the end when the reader, along with the townspeople, learns that this apparently normal and conservative old woman has been doing something really insane.
