Idril, Elenwë and Tuor.

SV note: I feel the need to point out that Elenwë is not depicted as child-sized here. Tuor canonically is the tallest of the Edain - even taller than Elendil, whose height is given as almost 2.5 rangar. (A ranga is 38 inches, so Elendil was almost 7'11" / 241.3 cm.) Idril is taller than her mother, since Idril's father, Turgon, is among the tallest of the Elves. Elenwë would be around 6' / 183 cm tall in this pic.
