Despite the recent postal strikes, today, the two certificates I requested from Lincolnshire County Council Register Office arrived; much sooner than I anticipated. My thanks to the Register Office.
The certificates seem to confirm my research, in brief:
Married on the 15th of September 1897, in the Parish Church at Marton, Lincolnshire.
Samuel's father is given as Charles DIXON 1827-Deceased. Mary's father is given as John Robert MAPLETHORPE 1851-Deceased.
Death Certificate: Samuel DIXON 1869-1906
Died at Upton (Upton-cum-Kexby), Lincolnshire, aged 37 years, of Phthisis Pulmonalis (tuberculosis of the lungs).
