Although an unfashionable second tier club, Llwynypia had already provided two Welsh internationals, Dick Hellings and Billy Alexander, and Llewellyn joined their ranks when he was capped in 1899.

Llewellyn made his debut for Wales against England in 1899, alongside Welsh greats Billy Bancroft and Gwyn Nicholls.

In 1904 Llewellyn was chosen to tour Australasia alongside fellow Welsh winger Teddy Morgan[5] under the captaincy of Bedell-Sivright.

He is remembered as a modest man who was an excellent captain for club and country and was one of the most devastating wing players in Welsh rugby history.
