The specimen seems to have been out and about for a good long while, in at least the Kay Robertson, Christensen, Spechels and Kessler collections. There are four different collection numbers (40 on blue square, 619 on tiny old German label, a 746 and a Kay Robertson 8962).

Childrenite was described from here by Brooke (1823) - Brooke, H. J. A. (1823) Q. J. Lit. Sci. Art. London, 16, 274-5. I read that Richard Talling handled childrenite from here from 1846 onwards.
