The information presumably isn't there or available for this website. Remember that the info provided is largely from family sources.
There are publications in Germany and indeed eleswhere where greater information is given but of course protected under copyright. You also have to take into account the sensitivities and privacy of the famillies involved, some are happy for information to be published, others feel that personal tragedy suffered is enough without raking over the past again. And some may feel that profit is being made out of their loss, and that that isn't right.
