OOPS!
Sorry folks, the cemetery we visited was actually VENRAY, not Overloon. I checked with friend's son earlier, before I made the post, he confirmed Overloon - but I've just checked again and it was definitely Venray, confirmed by the CWG records.
Pte Keel was initially buried at Venray, in an orchard according to the article. The body was later moved to Overloon Cemetery. The two places are very close to each other, ( I actually hought we were at Overloon...) but I wonder why Venray was not chosen as his resting place?
So close, but not as close as I thought.
Sorry again for the mix-up!
