Omeljan Pritsak further considered the connection of the name of Dulo clan with the name of the old Xiongnu ruling house 屠各 "Tuge" (in Old Chinese "d'o-klâk"). This association could further prove the link between Xiongnu and Huns (as well Huns and Bulgars). Peter B. Golden surmises that the Xiongnu tribal surname 獨孤 Dugu (&lt; "d'uk-kuo") or 屠各 "Tuge" (&lt; "d'o-klâk") possibly reflects underlying Turkic *"Tuğqu" or *"Tuğlağ" "tribe of the tuğ?" yet still considers the Turkic association as speculative.
