Which president was adopted?

Similarly, Bill Clinton started like as William Blythe and changed his name to Clinton when he was adopted by his mother's second husband, Roger Clinton.

Rumor has it that Gerald R. Ford Jr. was adopted, but this is not true. Ford was born Leslie Lynch King to Leslie Lynch King Sr. and Dororthy Aver (Gardner) King. Dorothy left Leslie Sr. sixteen days after Jr. was born due to threats of violence and death by Leslie Sr. She moved first to Oak Park, Illinois, then to East Grand Rapids, Michigan where her parents lived. There she met Gerald Rudolf Ford. She divorced Leslie King Sr. in 1913, and married Ford three years later on 1 February 1916. They began calling Leslie Jr. Gerald. President Ford was never legally adopted by Gerald Ford Sr., but he did have his name legally changed to Gerald Rudolf Ford, Jr. on 3 December 1935.
