Eusevia is a misspelling of Eusebia (in Spanish, V and B are both pronounced [b], so misspellings between V and B are very usual), the feminine form of Eusebio, a name from Greek origin, from the adjective
eusebes, "devout, pious, fearful of the divinity".
It is not related at all with Silvia (the Spanish form of Sylvia).
