Attested: Onna at position 40 in the Ravenna Cosmography
Where: Probably at Horsebridge, Hampshire, SU339305, where a Roman road crossed the river Test, because the Cosmography listed Onna between Noviomagno (probably Old Sarum, not Chichester) and Venta velgarom (near Winchester).
Name origin: Endlicher's Glossary explained “Gaulish” onno as Latin flumen ‘river’, which has prompted discussion of a possible origin from PIE *(s)nau- ‘to flow’ and links with Latin unda ‘wave’ and with ancient river names ending in -na.
