Give up then?
OK, Donatella is the wife of Alessio Fabbricatore, an Italian cave diver. We went cave diving over there years ago and she looked after us marvellously, so that aven was named after her.
Balcombe's Way is indeed named after Graham Balcombe of the CDG. Many years ago when battery drills were just a glint in cavers' eyes we were hand bolting up the massive avens in Peak's Far Sump Extension. I happened to be talking to him about this and how we wished we had a battery drill. Graham calmly produced a cheque and said OK, go and buy yourselves one then! It was an incredibly generous gesture and we felt we had to give the above name to the passage in question. So you see, this was before Graham died.
Here's another one - why was The Total Perspective Vortex so named?
