The early Lowland Logans originated from Galloway. It is documented that two of them were killed in Spain in 1329 on their way to the Holy Land with the heart of King Robert I (the Bruce).

Sir Robert Logan of Restalrig (d. 1606) had his bones exhumed and paraded in Parliament so that he could personally be convicted of treason. The Highland Logans claim descent from the Logans of Drumderfit in Easter Ross. The Highlander Logans are closely linked to the MacLennan clan.
