Ruchama is from the Hebrew רֻחָמָה (Ruḥāmāh — compassionated, mercifully loved) — from Hebrew racham (womb/mercy). Ruchama is one of the Hebrew feminine names — central to traditional Jewish heritage.
Ruchama 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 Ruchama reduce to 2, The Peacemaker. This is a traditional interpretive system, not a factual claim about the name.
