For those known as Hamadryades, a tree was born with her birth to which her life was tied. While the tree flourished, so did its resident nymph, but when it died she passed away. They were wed by the men of the Silver Age--in the time before the first woman was created--and from them mankind was descended. The eldest of these were daughters of the five Daktyloi Dactyls and five Hekaterides Hecaterides. Subsequent generations were descended from these elder Oreiades and their brother Satyroi Satyrs.
