Inspired by Andy's question, I trawled the archives and came up with the following for GB. I don't know enough about Ireland to stick my neck out there. You'll probably say that some of these aren't true links, but at least it's a basis for argument.
Perranporth (1927), Trevose (1924), Hartlepool (1906) (part links), Prince's (1906), North Shore (1910) (part links), Caldy (1907) (part links), Hillside (1911), Hoylake Municipal (1933), Southport & Ainsdale (1906), Warren (1911), Gorleston (links?) 1906, Bamburgh Castle (1904) (part links), Dunstanburgh Castle (1900), Magdalene Fields (1903), Turnberry (1906), The Glen (1906) (part links), Prestatyn (1905), Abersoch (1907), Nefyn (1907), Porthmadog (1905), Pwllheli (1900) (part links), Anglesey (1914), Holyhead (1912), Pyle & Kenfig (1922).
One of our outstanding links courses dates from 1947 - Southerness. We never seem to hear about it on GCA. I think it is superb, but what do others think? By the way, I love Birkdale and have said so before on GCA, but I always issue a caveat before recommending it to others.
