Rylee is the modern American feminine spelling of Riley — from the Irish Raghallaigh (courageous, valiant). Rylee Goodrich — American TikTok creator. Rylee Saunders — American gymnast. Rylee Bonaventura — American athlete. The Irish surname Raghallaigh is associated with the Connacht province in western Ireland; the name's modern surge as a feminine given name in the US parallels the broader Irish surname-to-given-name trend (Kennedy, Reagan, Cassidy, Quinn).
Rylee 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 Rylee reduce to 2, The Peacemaker. This is a traditional interpretive system, not a factual claim about the name.
