This sounds and looks like an Anglicised form of Heinrich, except unlike Henry, it was derived from the original Germanic form and not the Latinised form Henricus.
My little brothers' name is Hendricks and I brag about it all the time. Who meets someone with the first name Hendricks? I don't love the name, but it's so rare to meet someone with the name Hendricks/Hendrick, spelled that way. It certainly makes up for its spiceless pronunciation with its huge amount of rarity.
