Silvi is from the Chuvash Силви (Silvi) — Chuvash feminine name. Silvi is one of the Chuvash feminine names — central to traditional Chuvash Indigenous Volga Turkic heritage. Chuvash feminine name reflecting Indigenous Volga heritage.
Silvi does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.

In Pythagorean numerology the letters of Silvi reduce to 8, The Visionary. This is a traditional interpretive system, not a factual claim about the name.
