Notes:

Nathaniel Charles Jacob Rothschild, Fourth Baron Rothschild, current head of the dynasty, married Mary Serena Dunn, whose mother was Lady Mary Sybil St. Clair-Erksine, the daughter of James Francis Harry St. Clair-Erskine, 5th Earl of Rosslyn. The title of Earl of Rosslyn was created in 1801 for Alexander Wedderburn, 1st Baron Loughborough, the former Lord Chancellor. The earldom was created with special remainder to his nephew, Sir James St Clair-Erskine, who was Grand Master of the Grand Lodge of Scotland, on behalf of King George IV. The Erskine family were the hereditary Earls of Mar. They are descended from Robert I Erksine, who married Elizabeth Stewart, the daughter of Robert II of Scotland, the son of Robert the Bruce’s daughter Marjorie and Robert Stewart. John 5th of Erskine was guardian of King James V, and afterwards of Mary, Queen of Scots. James V had an illegitimate child through his daughter, Margaret, named James Stewart, step-brother to Mary Queen of Scots. In 1565, Queen Mary made Margaret’s brother, John 7th Earl of Mar.
