And bookies are already offering odds of 25 to 1 for baby Rhys to play for Wales.
Taylor, capped 46 times, played a key role in the Wales team that took the World Cup by storm with their try-scoring exploits against the All Blacks and champions England.
And he has rounded off a near-perfect autumn by returning home from Down Under just in time for the arrival of his first child who weighed in at a healthy 7lbs 3oz.
Wife Anna said: “We’re both delighted. We’re a little bit tired and the last few days have been pretty hectic but Rhys is healthy and we’re very happy.”
Asked if Rhys could emulate his father in playing for the British Lions, Anna replied: “I’m sure Mark will be playing with him in the garden but I hope his first birthday present isn’t a pair of boots.”
South Wales bookmakers Jack Brown were understandably wary of offering long odds on Rhys wearing the red jersey considering the Taylor bloodline.
Rhys’ Grandfather Ivor played more than 400 games for Newport and Pontypool while uncle Paul also played for Pontypool.
