on this site saul charts for warwickshire there is a henry with his spouse name as jane flavel 1833-1905
in my reseach i have found a wedding for henry and a hannah flavel form weston (under wetherly) 15th dec 1851 but can not find any proof that hannah changed her name to jane apart from jane gives her place of birth as weston ?
the only jane i can find from weston is a jane sumner dob 1796 and she is a witness the wedding certificate ?
hannah gives her place of residence at time of wedding as claverdon farm, i can not find any trace of this on any old maps ?
thanks
