There are several instances of Committal to the Fleet for meddling with Marriages. One or two will suffice:--1731. "Thursday, the Master of the Rolls committed a Clergyman to the Fleet for marrying a young Gentleman about 17 years of Age at Eaton School, and intitled to an Estate of £1500 per Annum, to a Servant Maid: and at the same time committed the person who gave her in Marriage. His Honour had some days since sent as Prisoner to the Fleet, the Person who pretended to be the Youth's Guardian, and who had given a Bond to indemnify the Parson."

1735. "Two Sisters were committed to the Fleet prison, by an order of the high Court of Chancery, for drawing a young fellow into marriage, he being a ward of the said Court."

Dec. 28, 1734. "Last Saturday Night Mr. D---- late Valet de Chambre to a certain Noble Lord near Soho Square, went away, as was suspected, with his Lordship's Niece, a young Lady not yet of Age, and a Coheiress to a very large Estate. It seems they took a Hackney Coach soon after they got out of Doors, and upon strict Enquiry, the Coachman was found out, who declared that he took a Gentleman and a Lady up at such a Place, and set them down at the Fleet, and by the Description he gave it appeared to be the two Lovers, who may therefore be supposed to have been married and bedded that Night. A Warrant was immediately obtained for apprehending the Supposed Bridegroom, and he was accordingly taken in Bed with his Lady, at a house in Queen Street near Guildhall, on Wednesday Morning last, and immediately carried to Poultry Compter, and the Lady was carried off by her Friends. In the Afternoon he was examined, and afterwards re-committed to the same Prison. So that it seems he is to suffer for endeavouring to get himself a _Rich Wife_, which is a Practice followed by all the young _Gentlemen_ of _Quality_ in England; but the Difference is, _That this young fellow has married, or endeavoured to marry an Heiress without the Consent of her Friends, whereas the other generally marry or endeavour to marry Heiresses without their own Consent._ It has since been found out that they were married by a Roman Catholic Priest."

There was a faint-hearted protest on the part of the Fleet authorities, against the Marriages, but I can find no attempt at prosecution, other than for marrying without a stamped licence, in spite of the following advertisement:--
