RD-EX-66:
Tol-Galen is only twice mentioned in the HoME Series, and all these phrases are in the Quenta Silmarillion in HoME V. The first is a footnote to chapter 9: Of Beleriand and its Realms. In the discription of Ossiriand the footnote reffers to the name Adurant. It was later inserted and reads:

And at a point nearly midway in its course the stream of Adurant divided and joined again, enclosing a fair island; and this was called Togalen, the Green Isle. There Beren and Lúthien dwelt after their return.

The second is in the conclusion of the chapter 15 The Quest of the Silmaril 3. It reads:

It is said that Beren and Luthien returned to the northern lands of Middle-earth, and dwelt together for a time as living man and woman; for taking up again their mortal form in Doriath, they went forth alone, fearing neither thirst nor hunger, and they passed beyond the rivers into Ossiriand, and abode there in the green isle, Tol-galen, in the midst of Adurant, until all tidings of them ceased. Therefore the Noldor afterwards called that land Gyrth-i-Guinar, the country of the Dead that Live, and no mortal man spoke ever again with Beren son of Barahir; and whether the second span of his life was brief or long is not known to Elves or Men, for none saw Beren and Luthien leave the world or marked where at last their bodies lay.

Both will surely be used in their proper place. Thus if we wont give the info that Beren and Lúthien dwelt on Tol-Galen in our current chapter again, I would suggest we use the passage from Sil77.
