The story of Ronaldo
Rögnvaldr was carried by Norse earls of Orkney and kings of the Isles, and Scotland kept it as Ronald. Portuguese and Brazilian naming produced Ronaldo, which two of the most famous footballers of the last thirty years have carried. It appears in the American registers and is in current use.
Meaning
ruler's counsel
Through Ronald, from the Old Norse Rögnvaldr — regin, 'counsel' or 'the gods', and valdr, 'ruler'. Norse settlement in Scotland gave Ronald; Portuguese and Spanish took Ronaldo from the wider European stock. Both elements are ordinary and the meaning undisputed.

Ronaldo's later chapters haven't been written yet, so we borrowed them: Alvis climbed just as high around 1912, and its whole arc is on record. Line the two peaks up, and Alvis's path sketches the road Ronaldo is walking now.
