Glorfindel?
 

Was the Glorfindel in Rivendell the same one as the Glorfindel of Gondolin who helped Tuor and Idril escape with their son? :confused:

You can use the search-function: ;)

a quick search gave me these links, that may help you and your question:

here, there or just here

Not intentionally; Tolkien calls his case a result of the "random use of the names found in the older legends". In the Glorfindel essay in Late writtings, HoME XII, he identifies several problems with the "second" Glorfindel (he cannot linguistically fit his name into Sindarin or Quenya, nor can he make Glorfindel to be of any other clan but the noldor). He also can't call this a name coincidence, since it doesn't occur with any other major elvish character.

Sharku has written a full explanation of this on the Barrow-Down's Middle-earth FAQ.

Thanks! ;)
