Attested: Caesar Bello Gallico 5, 21 Segontiaci
Where: One of the British tribes, presumably in the south-east, who sent embassies to surrender to Caesar.
Name origin: As R&S explained, Segontiaci might not be a regional or functional description, but rather a clan name for followers of Segontius. That personal name is well attested on epitaphs: Delamarre (2007) listed 7 instances, posted online here, including RIB67 in Britain. Segontius and similar names were especially common in parts of Iberia, where their derivation is uncertain, as partially discussed under Seguntio. In France, and possibly elsewhere, such names were interpreted as from Latin secundus ‘second’.
Notes: Seg- in personal and tribal names is commonly traced to a proto-Celtic *sego- ‘victory’, from which it is inferred that those name bearers were Celtic speakers. However, PIE *segh- ‘to hold’ developed in that direction more in Germanic (as in Sieg ‘victory’) than in Celtic (as in Irish seg ‘strength’) and shows up in early British names such as Segedunum and Isca (possibly from Greek ισχω).
