Who in Gondor had "dealings with the Elves" ?

[Inziladun]

I remember this coming up before. That was a good thread, and seemed to cover most of the necessary points.
All I can really think to add is the idea that maybe when Faramir said this:

'Yet, there are among us still who have dealings with the Elves when they may, and ever and anon one will go in secret, seldom to return.'

he might have been thinking of Aragron in his Thorongil guise, when the latter had served in Gondor some years before. Faramir never met 'Thorongil' but the latter had been highly esteemed by Faramir's grandfather, Ecthelion II. There's no direct indication in the books that 'Thorongil' ever admitted having been to Lórien, but I don't think it out of the question that he might have told someone that, or they might have read between the lines. And maybe he'd said something along the way about returning there one day, 'for there my heart lies', or something to that effect. It's a thought, anyway.
