Hi Jane,
I can't help with the marriage but is this the family tomb?
Underneath are deposited the remains of
George OLDBURY, late of Eardington within this Parish. Gent, who died 3rd April 1809 in the 63rd year of his age.
Also
Joan, wife of the said George OLDBURY, who died 30th June 1824 in the 84th year of her age.
Also of George OLDBURY, Gent, son of the said George and Joan OLDBURY who died 17th November 1845, aged 62 years.
Also Margaret Anne OLDBURY, daughter of George and Mary OLDBURY who died 14th January 1851, aged (15 or 75?) years.
From the Monumental Inscriptions at Saint Mary Magdalene, Quatford near Bridgnorth that I transcribed for the Shropshire Family History Society.
Hope it helps,
Gwynne Chadwick
