The ninth Baronet succeeded as heir of entail and assumed the additional surname of Maxwell.
The tenth Baronet sat as Member of Parliament for Glasgow College and was also made a Knight of the Thistle.
His daughter, Dame Anne Maxwell Macdonald (1906–2011) was recognised by Court of the Lord Lyon in 2005 as 11th holder of the baronetcy under the 1707 remainder, and therefore succeeded her father in 1956.
On her death in 2011, she was succeeded by her eldest son John Ronald Maxwell Macdonald, born 1936.
[citation needed] The heir apparent is the present holder's son, Fergus John Logie Maxwell Macdonald (born 2007).
