The IGI, as you say, is on the LDS site, but is far from being comprehensive and for Hunts and Cambs is pretty sparse for controlled extracts which are the only reliable entries, and even those should be checked against the parish register. But any entries which state in the Message section "Record submitted by a member of the LDS church" should be treated very circumspectly - you will see that both Eliza and Joseph are on the IGI as being baptised in Ellington.
Beds is pretty complete up to 1812, but there are gaps after that, and I don't think Keysoe is complete. You can get an idea from Hugh Wallis's site
http://freepages.genealogy.rootsweb.com/~hughwallis/IGIBatchNumbers/CountryEngland.htm#PageTitleThe death entry you have found in 1902 fits perfectly - but I can't find her in 1901 either!
I've been through Eaton Socon in 1841 without any trace - although it's a fairly large parish any the quality was none too great, so I can't guarantee that I didn't miss it! I couldn't see William Baker in Brampton either
Good luck
