Pat, Rhydderch was a fairly uncommon Christian name and the sons of a Rhydderch would be ap Rhydderch, which when the ap was dropped became Prytherch. This was Anglicised to Protheroe. The process of Anglicisation was gradual, and started in the Welsh Counties closed to England and moved gradually Westwards. Even in the rural areas of Cardiganshire, Meirionethshire and Caernarfonshire most had adopted a settled surname by 1850 at the latest. Pembrokeshire was Anglicised from an early date, and most had adopted a settled surname by the late 18th Century. You may well have identified the correct family, but it would be a very unusual if not an unique occurrence for the change to happen this late.

I told her the books on Welsh surnames show that the name Prothero comes from ap Rhydderch. So the Rhydderch family I found in 1881 looks to be the right one for her Dorothy Prothero.
