I grew up in all around northern Spain. We have deep Spanish roots there. Specifically, from Basque Country, Asturias, Cantabria, and Galicia. I was looking up the name Elivier on nameberry and it dosent show up. I’m saddened, this name where I’m from is popular because of a noble family that resided in these regions. Its important to note that, in Basque county they use it as a feminie take on the [name_m]French[/name_m] [name_m]Olivier[/name_m]. Pronounced E-liv-ee-air with the same meaning (olive tree) just a Basque Spanish twist.
