The Buckinghamshire County Council has an online website for searching and requesting Buckinghamshire Marriage Licenses.

“Marriage by licence allowed a couple to circumvent the usual system of the calling of the banns. Records covering c.15,000 such marriages in Buckinghamshire between the 17^th and 19^th centuries appear in this index. …Often we have the bond, by which the groom and one other agreed to pay a fine in the event of the marriage proving to be illegal. Other records also sometimes survive as well or instead. Most common is the allegation (in which the groom declares that there is no impediment to the marriage). The licence itself rarely survives.”
