Brian Lawson's burial index is here:

but Ramsey is not included. Many Ramsey deaths are recorded in Maughold, and some in Lezayre, but I can't see Eleanor's burial in Maughold. Could she be one of the Braddan ones? There were some institutions there where many Maughold people died (old age, etc.). Otherwise you will need to look at Ramsey parish registers on LDS film or in the MM Library, and you need an accurate age for her from earlier censuses. Aged 80 in 1871 doesn't match b.1799.
