Great overview. I'm using it, together with supporting sources, to update Wilding's wiki article. Found some additional info on Wilding's 1910 tournament win in The Netherlands.
[Date?] Scheveningen, The Hague, Holland (Clay)
FI: Anthony F. Wilding (NZL) d. [????]
13 August 1910 (date of final)
FI: Anthony F. Wilding (NZL) d. Borman (BEL) 6–2, 6–1, 6–1
The article mentions 'Borman' and not 'De Borman' but I'm assuming it refers to Paul de Borman
