I have a couple who seemed to have run away to get married from Essex to London, he married his sister in law and back in the village the following year on the son's baptism the vicar had written about it not being a legitimate marriage, so I suppose they did it on the quiet so they didn't get found out, but of course they didf, only reason I can think of as neither of them were Londoners, they were country folk
