Probably a modern combination name, possibly influenced by Her- and -lane elements with a surname-like style.
Herlane is probably a modern combination name, possibly influenced by Her- and -lane elements or by the sound of surname-style forms. Because its etymology is not fixed, the name reads as a contemporary invention shaped more by cadence than by inherited history.
That gives Herlane a smooth, surname-like polish and a quietly individualized feel. It sounds tidy, modern, and slightly formal without being stiff. Names like this often work because they suggest structure and originality at once, and Herlane does exactly that.
