Sources from the French Huguenot settlement of Fort Caroline, established in 1564, record a chief named Houstaqua, whose name is probably a variant of Yustaga. The French understood that Houstaqua and his neighbor, Onatheaqua (probably a chief of the Northern Utina), lived to the east of the Apalachee. However, they thought they lived near gold-bearing mountains (the Appalachian Mountains, which the Europeans thought extended into the Apalachee Province). French soldiers visited the Yustaga on two occasions, exchanging gifts with the chief and sojourning among his people for several months. The French reports credited Houstaqua with 3000 to 4000 warriors.
