Please could someone double-check this Braddan M.I. entry for me.
I found it on a family-tree website (http://junior.apk.net/~ctd/d0000/g0000092.html#I1406 ) but some of the dates/ ages just don't make sense when put in context:

Anne (Quiggin) GWANE [sic]
BIRTH: 1813
DEATH: 17 MAY 1845, Braddan IOM
Braddan MI Old Yard South page 38 #519:
To the memory of Robert Quiggin of Douglas who departed this life the
10th of June 1811 aged 57 yrs. Also Eleanor Quiggin wife of the above
named died 11th of April 1845 aged 88 yrs. Also John Quiggin son of the
above who died June 16th 1818 aged aged 59 yrs. Also Elizabeth Quiggin
wife of the above John Quiggin died April 1 1825 aged 41 yrs. Also Ann
