編年史中威塞克斯的早期歷史被認為是不可靠的,有重複的事件報導和看似矛盾的信息[22]。大衛·鄧維爾(英语:David Dumville)認為徹迪克真正的統治日期是538年至554年。一些學者認為,徹迪克是在巴頓山戰役(英语:Battle of Badon)中被英格蘭人擊敗的撒克遜領袖,可能在490年(也可能更晚,但不遲於518年)戰鬥。如果鄧維爾是正確的,情況就不是這樣,而其他人將這場戰鬥誤以為是埃爾或另一位撒克遜領導人,因此威塞克斯王國的起源似乎比仍存在的傳統版本提供的資料更複雜[23]。
一些學者甚至認為徹迪克是一個純粹的傳奇人物,但這是少數人的看法。《盎格魯-撒克遜編年史》是徹迪克的最早來源,於9世紀後期編纂而成。雖然它可能確實記錄了威塞克斯建立的現存傳統看法,但其間的400年意味著不能假設該資料來源是準確的[24][25]。史冊《盎格魯-撒克遜編年史》,以及該來源對後來國王記載中的家譜血統,都描述了徹迪克由他的兒子金里克繼承。然而,作為編年史手稿序言的族譜君主名單反而在他們之間插入了一代人,表明徹迪克是克里奧達(英语:Creoda of Wessex)的父親和金里克的祖父[26]。
