(For etymology of the surname, see Earl De La Warr§Etymology.) The English then began to call the Lenape the Delaware Indians because of where they lived.
Swedes also settled in the area, and early Swedish sources listed the Lenape as the Renappi.
As such, a person's mother's brothers (the person's matrilineal uncles) played a large role in his or her life as they shared the same clan lineage.
Lenape kinship system has matrilineal clans, that is, children belong to their mother's clan, from which they gain social status and identity.
The mother's eldest brother was more significant as a mentor to the male children than was their father, who was generally of another clan.
The two groups were sometimes bitter enemies since before recorded history, but intermarriage occurred — and recent scholarship exists saying that both groups have an oral history suggesting they jointly came east together and displaced the mound builders culture.
In addition, both tribes practiced adopting young captives from warfare into their tribes and assimilating them as full tribal members.
