Families covered: Blackader of Blackader, Blackadder of Tulliallan

There are conflicting stories of the origins of this family. Some web sites assume descents from people of similar name from the 13th century, apparently with little or no justification. According to www.electricscotland.com, the family name means Blackwater, with adder coming "from the Cambro-British awedur, signifying 'a running water'." That web site, which is generally reliable, suggests that the family took its name from "the stream of that name in the Merse division of Berwickshire" having defended the area "towards the middle of the fifteenth century ... against the incursions of the English" and in reward been granted land by King James II. However, that electricscotland site loses some credibility by suggesting that the Sir Patrick who married the heiress of Tulliallan was son of Andrew (and brother of the Sir Robert whose daughters were forcibly married to Homes, with Andrew being shown as son of Cuthbert who was granted land by James II) rather than son of a Sir Robert of that ilk, which is widely supported. The uncertainty this causes means that the first few generations shown below should be viewed with some caution.
