One of the witnesses to the marriage of George Smith was William Cutler. He probably married Catherine Smith in 1837.
Both were of Swannington but Catherine was a spinster. However, she gave her father as Thomas Price.
Although born c 1817, she seems to have been baptised in Griffydam on 26th October 1834, born 15th November 1817, daughter of Sarah Smith, a spinster of Swannington. Her mother, like Sarah Glover, was also the daughter of James and Mary Smith.
I suspect that George and Catherine were siblings, but definite proof as yet.
In 1851, Catherine was a widow and one of her children was James Smith Cutler.
