Marriage ceremonies in London were easily available at a wide range of locations before Hardwicke's Marriage Act put a stop to clandestine marriages in 1754. Not constrained to their own parish church, many wed at centres of clandestine marriage such as the Fleet, or in other churches by licence. For particular parish populations, focusing mainly on the suburban majority but with comparisons with the mercantile city centre, this paper considers the relationship between demographic, geographic and social factors (age, residential location, and propensity to engage in premarital sex) and choice of marriage location between 1610 and 1753.
