I had a little scout around on the old (and new) maps. Couldn't see much, but here's some stones if you like - there was a stone marked at TL47661038 on the 1870 map. There are new houses near it but it's in a strip of trees, maybe they're old and maybe it's still there. That's where a little road goes over a little stream / ditch.
Also there are two stones marked at TL48211002, and that's a boundary of various sorts, it's where two footpaths split. That's in the countryside a bit more so maybe they'll be there.
They're all rather far from your barrow. So I'm certainly not promising they are anything at all! Let alone even there. But it's fun to go for a walk in the spring anyway is it not :)
