[2][3] Exceptionally little is known about the Icafui, other than their general location and the fact that they spoke a dialect of Timucua called "Itafi" along with the Ibi.

[4] The Icafui are described living on the mainland east of the Ibi, Yufera, and Oconi, which would correspond to a homeland on or not far inland from the Georgia coast between the mouths of the Satilla and Altamaha Rivers.

[5] Deagan specifically narrows this range to the mainland opposite to Jekyll Island, with a northern boundary in the vicinity of the Turtle River.

[3] The villages of Xatalano, Heabono, Aytire, Lamale, Acahono, Tahupa, Punhuri, Talax, Panara, Utayne, and Huara[5] are named as settlements "of the pine forests of the interior lands who are subjects of Doña Maria (of Tacatacuru on Cumberland Island)"[3] which may have been affiliated with the Icafui, but could also have been Mocama.

[2] The tribe is not mentioned post 1604, and was likely destroyed or displaced by the Yamasee in the early 17th century.
