Who was the first of the young women to migrate?

Umm Salamah, Hind bint Abi Umayyah, Mother of the Believers, may Allah be pleased with her, was the first woman (borne in a litter) to emigrate to Medina, according to the widespread and most accepted view among scholars. It was also said that it was Layla bint Abi Hathmah. She and her husband were the first to emigrate to Abyssinia.
