The Rig Veda Book 10 Verse 85 describes the bridal of Sun-god's daughter who is called Surya as well:
6 Raibhi was her dear bridal friend, and Narasamsi led her home. Lovely was Sūrya's robe: she came to that which Gatha had adorned.
7 Thought was the pillow of her couch, sight was the unguent for her eyes: Her treasury was earth and heaven ẉhen Sūrya went unto her Lord.
8 Hymns were the cross-bars of the pole, Kurira-metre decked the car: The bridesmen were the Aśvin Pair Agni was leader of the train.
9 Soma was he who wooed the maid: the groomsmen were both Aśvins, when The Sun-God Savitar bestowed his willing Sūrya on her Lord.
As far as I am aware the sun-god had two daughters Yami & Tapti but I haven't read of them having any association with Soma. So I want to know who the sun-god's daughter was whose marriage is being talked about here?
