Thanks, I also have some other strange profiles in this tree:
Henry Stewart
Adam Stewart
NN Halcro
and several NN's.
The Earl of Carrick......He had married at Chelsea in 1604 Lady Elizabeth Howard, daughter of Charles Earl of Nottingham and widow of Sir Robert Southwell. They had one child, Lady Margaret Stewart, who married Sir John Mennes and became the ancestress of the Lords Willoughby de Broke. Carrick also had two natural children: a son, Henry Stewart, who received a grant from his father of certain lands on Eday, and a daughter (name unknown), who married William Craigie of Gairsay. As he had no legitimate son, the earldom of Carrick and lordship of Kinclaven became extinct on his death,
This wikipedia stuff is maybe not right - but all the NN's and the Adam's are certainly wrong.
