My Fair Gentleman — Nancy Campbell Allen

Jack would rather be at sea than fixing the mistakes of his grandfather, the late Earl of Stansworth. Instead, he finds that inheriting his grandfather's wealth and title and securing the welfare of his sister and mother means joining the ranks of high society and living with the aristocracy.

Luckily, Ivy Carslisle, the granddaughter of a dear friend of Jack's late grandmother, is willing to teach him etiquette and properly introduce him into society. Jack soon learns that his challenge isn't surviving his new lifestyle but surviving the conspiracies against him as well as keeping himself from falling madly in love with his new tutor.
