The name 'Khoroshko' is formed using a productive model with the suffix -ko from the adjective 'good' (хороший). This name, like Velychko or Hlushko, was originally exclusively familial and domestic. Currently, there are insufficient grounds to consider that it has echoes of the name of the ancient deity 'Khoros'. However, the oldest written record of this name appears as 'Khorosko'. Notably, in 1600, the voivode of Lutsk, Konstantyn Khorosko, was named so (source: Archive of YUZR, vol. 1, page 97; Tup 416).In the records of the 17th century, various individuals are mentioned with the name Khoroshko. For example, Ivan Khoroshko was noted in 1603 (source: KZS II 103); in 1649, Cossacks from different regiments were referenced: Antypa Khoroshko from the Bila Tserkva regiment (source: RVZ 70), Semen Khoroshko from the Cherkasy regiment (source: RVZ 92), Gavrylo Khoroshko from the Uman regiment (source: RVZ 220), and another Semen Khoroshenko from the Cherkasy regiment (source: RVZ 69).Interestingly, the patronymic from this name, indicating the son of Khoroshko, was recorded even earlier, in 1552, when the Kyiv townsman Seko Khoroshenko was mentioned (source: Archive of YUZR, vol. 2, page 1115).
