If you have the banns read in an Anglican church for three several weeks before you get married, the wording is, or at least used to be, along the lines of
"I publish the banns of marriage between X, bachelor of the parish of Y and Z, spinster of this parish. This is the first time of asking. If any of you know any cause " etc
My guess is these spinsters are not usually old! Just unmarried. I used to think it meant something to do with spinning, which I suppose might be the origin.
