Hi Jack,
It does seem to be coming together - I'll be happier if someone can account for those other people on the same marriage page in Uxbridge, but perhaps I'm being overly cautious!
Now that you've confirmed the Ann Plumridge was unmarried - it also looks as though she was Rebecca's sister, which would explain why Charles was living with her in 1841. What it doesn't explain is why we can't find a marriage between a Rebecca Plumridge and John/George Goodwin and can't find Rebecca (+ possibly her husband if still alive) on the 1841 census. Did you try other counties or just Bucks? I don't have a sub with Ancestry so my hands are tied as far as the censuses go.
With us not being sure whether father's name was John or George, it's very hard to identify a death, but I did come across this one.
Eton Reg District June Quarter 1844 John Goodwin Ref. 6 251
I'll leave it up to you whether you think it worth taking a punt and sending for the certificate. Do you know about the reference checking service they offer? You can put in a detail (e.g. occupation has to be 'servant') and if the certificate doesn't match that reference, they'll only charge you £3 instead of the £7 for the actual certificate.
Another route you could take would be to ask Bucks FHS for a name search - they do them from databases covering baptisms, marriages & burials and they're very reasonable. That's assuming the relevant missing events took place in Bucks of course.
