When did the last of the High Elves leave Middle Earth ?

[The Mouth of Sauron]

The fact remains that after Elrond, Galadriel and Gandalf left Middle Earth, there were still in total many thousands of Elves who remained there who hadn't yet sailed, who lived in at least the following locations :-

- west of the Shire
- Rivendell
- Woodland Realm, Mirkwood
- Lorien
- East Lorien, Mirkwood
- Ithilien

It's also possible that some elves may have been in the far east of Middle Earth, having never made the journey westward throughout the ages.

So did they all sail eventually ?

My feeling is that all did not. The Silvan Elves had not heard the Sea's call, and they seemed quite content to continue on in their forest realms as long as they could. As a comparitively simple and rustic lot, probably some of them were uninformed as to their ultimate fate in ME if they remained.
This ties into the Círdan question. If all Elves did not eventually sail into the West, either because of conscious refusal or ignorance of their plight, how would Círdan know when the 'Last Ship' was to sail? How long would he wait for the last two or three to make up their minds before finally deciding they were a lost cause, and leaving himself?
