Kayeleigh, a unique and melodic given name of Irish origin, means 'companion'. It is derived from the Irish word 'cailleach', which translates to 'hag' or 'old woman', but it is believed that Kayeleigh signifies a more positive aspect, perhaps referring to a wise and knowledgeable companion. The name Kayeleigh has gained popularity in recent years due to its distinctive sound and spelling, offering parents an appealing alternative to more traditional Irish names.
"Kayeleigh saw its highest popularity with 13 births in 2006, while the years 2002 to 2004 and 2009 to 2010 had a consistent interest with around 7 or 8 births each. The name's appeal seems to have declined since then, with only 5 births recorded in 2012 and 2016."
