Why are most woman in the play so fascinated by the name Earnest?

Wilde exposes this divide in scenes such as when Gwendolen and Cecily behave themselves in front of the servants or when Lady Bracknell warms to Cecily upon discovering she is rich. However, the play truly pivots around the word "earnest." Both women want to marry someone named "Ernest," as the name inspires "absolute confidence"; in other words, the name implies that its bearer truly is earnest, honest, and responsible. However, Jack and Algernon have lied about their names, so they are not really "earnest." But it also turns out that (at least in Jack's case) he was inadvertently telling the truth. The rapid flip-flopping of truths and lies, of earnestness and duplicity, shows how truly muddled the Victorian values of honesty and responsibility were.
