Attested:  RC Onna

Where:  Probably at Horsebridge, Hampshire, SU339305, where a Roman road crossed the river Test, because RC listed Onna between Noviomagno (probably Old Sarum, not Chichester) and Venta velgarom (Winchester). 

Name originEndlicher’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.
