His name is thought to mean "creative power", and as a proper name "Creator". Very early in Egyptian history, Re was identified with Horus, who as a falcon-god represented the loftiness of the skies. He was represented as a hawk-headed man or as a hawk. A combination of the two, Ra-Hoor-Khuit, "Re, who is Horus of the Horizons" showed the two as manifestations of the singular Solar Force.
Re was the father of Shu and Tefnut, grandfather of Nut and Geb, great-grandfather of Osiris, Seth, Isis, Nephthys and great-great-grandfather of Horus.
