History & Origin
Haidy is best read as a variant of Heidi, the affectionate German short form of Adelheid ('noble kind'). The spelling swaps in -ai- to lock the long-I sound, and it appears mainly in Latino and immigrant families in recent decades.
It was never common in the United States, given to only about twenty girls a year even at its faint peak around 2011, and it stays rare. A girl named Haidy then is barely a teenager now.
