Originating from Hebrew, the name Heiley is believed to mean 'cheerful'. It's a variant of the name Hallelujah, which translates to 'praise Yahweh'. In some cultures, it may also be associated with the flower heather, symbolizing beauty and good fortune.
"Interestingly, Heiley's popularity peaked twice - once between 2007 and 2010 with over a dozen babies each year, then again in 2012 with another peak of 13 births. However, it seems to have declined significantly since then, with just five or six births annually from 2019 onwards."
