Re: Re[2]: [tied] Santiago and James

The usual explanation is that Portuguese Diogo and Spanish Diego < *Didacus, perhaps through Vulgar *Diducus and Didicus. The Saint Jacob became Jacomus to distinguish him apart from Patriarch Jacob. In Portuguese there was many forms, and along XVI,XVII centuries the forms Jacome and Jaques were more common. But due an influence of (San)Tiago, Diogo was treated as equivalent of them, although his different origin. The patronymic of Didacus, Didaci, became Portuguese surname Dias (Spanish, Diez, Diaz). Today the usual form is Jaime in Portuguese, and in Brazil the name Tiago is very popular.

They are independent names. What I question is whether <Diego> actually can derive from <Jacobus> at all, or at least whether this source plays any significant role. Brian
