Imin
From Tolkien Gateway
Imin was the first Elf who awoke at Cuiviénen and one of the three Elf-fathers. His spouse was Iminyë.
Imin wandered with the other two Fathers, Tata and Enel until they found a groups of 12 sleeping Elves which he took with him. The Clan was named after him Minyar, the "Firsts".
He then refused to take the other Elves they found, waiting for a larger group. Eventually they found none other and his clan remained with only 14 members.
The clan was later named Vanyar.
