River BraanThe River Braan is a tributary of the River Tay in Scotland. Within the county of Perth and Kinross, it flows 11 miles eastwards from Loch Freuchie, near Amulree, and joins the River Tay near Dunkeld.EtymologyThe name Braan is likely of Pritenic origin and derived from *breμ-, meaning "bellow, bray, roar". A similar etymological root underlies the names of the rivers Breamish in Northumberland, England, and the Brefi in Ceredigion, Wales.
