Lady Janet Helen of Mar (born 31 January 1946), (née Lane, is the sister of Margaret of Mar, 31st Countess of Mar.[1]

Lady Janet was born Janet Helen Lane in Kenya, the younger daughter of James Clifton Lane (later Master of Mar and Earl of Mar) and his first wife, Millicent Mary Salton, who from the time of her marriage until her death was always known as Mrs Mary Lane and never, as has sometimes been stated, as the Mistress of Mar, a substantive title that can be used only by the senior heiress presumptive.

In 1959, the Master of Mar (who succeeded as Earl of Mar in 1965) was officially recognized by the Lord Lyon in the surname of Mar. His son David (Lord Garioch), and his daughters Margaret and Janet were also of Mar from that time onwards. Lord Garioch died in 1967, and Lady Margaret, the elder co-heiress presumptive of her father, succeeded as the 31st holder of the Earldom in 1975.

Lady Janet, the younger co-heiress presumptive, married Lt-Cmdr Laurence of Mar, RN (formerly Laurence Duncan McDiarmid Anderson) on March 22, 1969, and was known as Lady Janet Anderson for only a few months; from October 1969 she and her husband were officially recognized by warrant of the Lord Lyon in the style of Mar, the surname Anderson being formally abandoned. Laurence, who bears the Mar arms, differenced, by the Courtesy of Scotland, is Garioch Pursuivant of Arms.

The style of Mar is a "name of nobility" and should not be confused with Scottish territorial designations.

They have two daughters:

  • Elizabeth of Mar (b. 17 Jan 1970)
  • Catherine Jane Kelly (b. 13 May 1971), who under Scots Law retains her maiden name of Mar, married Stuart Kelly, by whom she has issue.[2]
