Irregular marriages were carried out in most cities during the 18th and 19th Century. The church always keen to prosper offered to marry couples for a fee without the usual trimmings and family involvement. No they were not Catholic or Nonconformists, but they were young. Reading Books they often refer to these irregular marriages where for a fee the minister would marry a couple without too many questions, ie Banns or Licences. Some of you will be aware of the Fleet marriages. Normally the couple would have had to reside in the area for a time period prior to marriage. Rent lodgings usually close to the church. Again not too many questions were asked as to how long they had been there. Such churches would carry out multiple marriages a day, more money for the church. Looking at the marriage register for St Martin's it appears there was a disproportionate number of marriages each day, even given the increased population. Also the witnesses were often link to the church as their names keep popping up. I just wonder if anyone else had come to the same conclusion St Martins was such a venue that couples seeking to marry outside of the family and away from prying eyes flocked to the St Martins to tie the knot.
