Those biographies already published in the Dictionary of National Biography were not included in DWB.
Fact is, as one who read the DWB to 1940 quite often, I have found a number of people mentioned HAD also been mentioned in the DNB - eg Lord Herbert of Chirbury, Robert Owen (reformer). Usually, where a DNB mentioned person appeared, it was usually the aspects of their lives most relevant to Wales that featured in the DWB.Cloptonson (talk) 22:15, 20 April 2016 (UTC)[reply]
