Helpful minister provides maiden names in register
Whilst searching for some maternal ancestors today, I had recourse to look at the parish register of baptisms for Elham, Kent, on the Find My Past site.
In order to ensure he was compliant with the law, the minister(s) started the particular register by including the mother’s maiden or previous name alongside that of the father, even if both parents were married! Unfortunately for us, the practice did not continue through the register!
