Are you certain that the crest belongs to a Page? A quick review of Fairbairn's Crests indicates some 210 family names from Acheson to Wynn, missing only the letters I, Q, U, X, Y, and Z (some are variant spellings, e.g., Page/Paige, Read/Reade, but that still leaves at least a good 150 or more) which bear the crest of "an eagle displayed" of some tincture.
If it is the Page crest, neither Fairbairn's nor Burke's General Armory is of much help. They each cite but Page or Paige of Devonshire, and Page of Chester (Burke's gives a date of 1711 for this), neither of which is in Ireland, where your Pages start.
>Who was entitled to bear this crest?
Because the crest of "an eagle displayed" is used by so many different families, without knowing the tincture (silver/white, gold/yellow, black, blue, red, green, purple, or ermine. Of the two Page eagle crests, one is ermine and the other is or [gold/yellow]), it's hard to narrow down the roughly 200 family lines entitled to use such a crest. And, indeed, as big as they are, neither Fairbairn nor Burke is comprehensive; there may be others who used this crest not listed in those volumes.
In any event, whoever used this crest would also have had a coat of arms, so that may be a line of inquiry for you. Additionally, the hallmarks (if any) on the silver pieces themselves may give clues as to when and where as well as by whom they were created, which also might help to narrow the search parameters for you.
I hope that at least some of this information is of some help to you. And, of course, if you have any questions about anything I've said here, please don't hesitate to ask.
