Plosive voicing is a common feature in Spanish evolution from Latin, then a
Sanct Iacob reanalized as Sanc Tiacob, that Tiacob could have derived into
Diago or Diego (how vowels have changed is not clear to me).

Well, I'm just guessing after I have no evidence suporting this nor I know
when those changes took place (voicing of voiceless stops and elimination of
voiced ones).
