The name Kacin is of Slavic origin, particularly from Croatian and Serbian roots. It's derived from the male given name Kaćin, which is a variant of the name Kaća, itself a diminutive of the female name Katarina (Catherine in English). While it's less common internationally, in parts of Eastern Europe, it carries a unique cultural significance.
"The name Kacin has seen a varied number of births over the years, ranging from a low of 5 to a high of 12. While there was a peak in 2013 with 12 births, it seems to have been an anomaly as numbers decreased afterwards, reaching another low in recent years with 6 births in 2022."
