Old Romanno Bridge

On our way back from Edinburgh to Cumbria we often stop to examine curiosities on the A701, usually highlighted by a geocache.
This is the old bridge in Romanno Bridge  built in 1774 to carry the Edinburgh to Moffat highway and bypassed in about 1970.  The tiny hamlet was the scene of a blood bath between gypsy clans in the 1600s but I can't find out where the name comes from. Could it be Roman? 

I'm adding some more details about the Gypsy skirmish if you are interested, taken from the Peebles Advertiser
-"It was close to this spot that in 1677 two gypsy clans, the Faws and the Shaws, returning from Haddington Fair fell out over the division of spoils that they had taken there. 
The resulting skirmish was a bloody affair resulting in the death of old Sandie Faw and his pregnant wife and the serious wounding of his brother George.
The remaining fourteen were quickly arrested by the Laird of Romanno, Alexander Pennecuik, taken to the Peebles tolbooth and subsequently sent to Edinburgh for trial which resulted in old Robert Shaw and his three sons being found guilty and hanged in the Grassmarket.
