Early name for Tol Brandir in Lord of the Rings drafts from the 1940s, glossed “Carrock” and also appearing as (deleted) Toll-ondu and Toll-onnui (TI/268, 285). It seems to be a combination of toll “island” and a lenited form of an otherwise unattested adjective gondren “✱of stone”, as suggested by Roman Rausch (EE/2.36).
