The meaning/history section states:
"Means "son of Kadyr". Notable bearers include father and son Ramzan (1951-2004) and Akhmad (1976-) Kadyrov, former President and current President of the Chechen Republic, respectively."
They have it backwards. Ramzan is the son and current president of Chechnya, Akhmad is his father/the former president of Chechnya.
