Charles Francis Adams, a son of John Quincy Adams, was almost nominated for President in 1872 by the Liberal Republicans (the anti-Grant faction) but lost out to Horace Greeley. His mother was born in London in 1775 to an American father and an English mother. His supporters in 1872 clearly did not see him as disqualified.
