Martha, wife of Thomas Ruel (variously spelled!) was buried in Walberton, Sussex - a village between Chichester and Bognor 1 Dec 1748

which would be fine, except
William Ruel married Martha Peachey, and
Thomas Ruel married Jane. I haven't investigated that far, but they may be brothers, as they both had children baptised in the same year:

Jane d Thomas & Jane bp 7 Jan 1745/6
Eliz, d William and Martha bp 30 May 1746
The vicar wasn't quite as bright as he might have been: when Thomas's son Thomas is bp, the vicar has to cross out Martha for the mother's name and insert Jane:

I am beset by omissions and mistranscriptions: only furious hunting turned up William and Martha's marriage, as the vicar was using up spare pages in an old register, and the entry hasn't been indexed, while a popular rendering of the name in indexes seems to be Buel.
Elizabeth appears to be William and Martha's last child, and William himself was buried in 1753.
Should the entry read
Jane wife of Thomas, or Martha wife of
William?
I am not even considering the possibility that there was a third couple in the parish!
