Bob,
Not aware of any Darwin links. Like you, be interested to know if there are any.
As an aside, the original course on the common has a 'review' section in Horace Hutchinson's "Famous Golf Links" but is not mentioned in Hutchinson's "British Golf Links" published just a few years later. Another golf linkage is that Hugh Alison went to school at Malvern College. The relationship between the College and WGC was very close back in those days so it would be difficult to imagine Alison not playing on the course on the Common.
