The name Lark was primarily masculine, with influence from Larkin, short for Laurence/Lawrence. However, now people are using it as a feminine name, so this should probably be categorized as unisex.

This name should be both masculine and feminine because it is traditionally a male name. However, I really like the name and it is on my short list. I'd use it for either gender.
