OK, have viewed it, Jenkins Row is listed after Bridgend Road, which is the main road through the village, so I would presume that Jenkins Row must have run off that, (if I'm wrong presuming that, I hope someone will correct me). There is also a Brook Row nearby which I don't think is an Aberkenfig address now. I will see some friends later who may know, so I'll get back to you later today/tomorrow.
