Stephen Grover Cleveland 22nd and 24th President of the United States 1837-1908
His crusade for political reform and fiscal conservatism made him an icon for American conservatives of the era. Cleveland won praise for his honesty, self-reliance, integrity, and commitment to the principles of classical liberalism. He fought political corruption, patronage, and bossism.
There might be a closer link, given previous genealogical studies which state he was a kissing cousin (which usually means a relative whom one knows well enough to kiss more or less formally upon meeting). However, I cannot confirm a closer link.
