I've been using research from some Pedigree documents and it will state:

"died s.p. before 15 Edward I, 1287"
"He died 22 Edward I, 1294"
"26 Henry 3, 1228"

How would you list the dates for those three examples?

Also, is this 'Maud' or 'Robert Hilton' concerning the will and 'proved' (which I assume is probated after death):

"MAUD, daughter of Robert Hilton, of Hilton, Esq., will dated 1 September, and proved 10 November, 1419"

Any assistance will be appreciated?
