No President of the US can be said to have been "elected by secession", unless possibly Washington himself, if the states ratifying the 1787 Constitution are considered thereby to have "seceded" form the old Confederation, but this is a very questionable notion. Jefferson Davis was elected President of the Confederate States after their secession in 1861, but was of course never President of the US.
Calvin Coolidge, the 30th President, was 48 when he was elected vice-president. He was 51 when he became President due to Harding's death. He was 52 when he was elected President in 1924.
