It lists Henry Evans as the bondsman and Tom Hughes as the witness. This is what The Legal Genealogist had to say about marriage bonds and bondsmen:
“When folks married without banns, however, particularly when they married some distance away from where they were known, there wasn’t the same opportunity in advance to have folks “speak up or forever hold their peace.” The bond then stepped into the breach.
What that bond actually was, then, was a form of guarantee that there wasn’t any legal bar to the marriage. Enforcing the guarantee was a pledge by the groom and a bondsman — usually a relative — to pay a sum of money, usually to the Governor of the State (or colony if earlier, or to the Crown if in Canada6), if and only if it actually turned out that there was some reason the marriage wasn’t legal.”
