One thousand marriage certificates from 1619 to 1660 in the Archdiocese of Canterbury show that only one bride was 13 years of age, four were 15, twelve were 16, and seventeen were 17 years of age while the other 966 brides were at least 19 years of age at marriage. And the Church dictated that both the bride and groom must be at least 21 years of age to marry without the consent of their families; in the certificates, the most common age for the brides is 22 years. For the grooms 24 years is the most common age, with average ages of 24 years for the brides and 27 for the grooms.&quot;
