Clann BORTHWICK
This ancient Celtic name was taken from lands the family occupied near Borthwick Water in Roxburghshire. In 1425, a Borthwick Lord served as a hostage in England as part of the ransom for the imprisoned Scottish King, James I. Mary Queen of Scots, and her third husband, Earl Bothwell, sheltered in Borthwick Castle after their marriage in 1567.
In about 1410, Sir William Borthwick acquired lands in the Borders and Midlothian, and not long after, members of the family became Lords in the Scottish Parliament.
