Thank you Patch86UK for your response, however, perhaps to the dismay of some and the glee of others, OSM isn't for invented/compromise names. 

My question was really out of curiosity & trying to to improve the quality of archaeological site type features in the local area.

Anyway I've added a link to wikidata on the way, which is an outlink that works on osm.org (unlike the Historic England ref), so I'm a bit happier that non tech savvy people can figure out what the archaeological site is describing.

Maybe Swindon Borough Council could put up some signposts or an information board so OSM can add a name to it...
