郞 is an older variant of 郎, combining 良 (good) with ⻏ (the village or place component). The character likely originally referred to a man of good standing associated with a place or title.
The left side 良 suggests goodness, and the right side ⻏ can be seen as a formal enclosure or place. Picture a good man in a distinguished setting: a gentleman.
For ロウ, imagine a gentleman in a row boat, rowing gracefully: row -> ロウ, and his good character shines.
