Are Mr Stewart and his wife divorced, and is she related to the
Pollock baronets?
The genealogical information I have on the Stewarts of Galloway is
from
Leo Van Der Pas:
http://worldroots.com/brigitte/royal/fatherofeurope/alexstewartdesc1694-5.htm
(go to the end for Andrew Clyde Stewart, his brother, cousin and their
children. Andrew has one son; his brother has two sons, and a cousin
has one son who is the eldest in the most recent generation!).
Also see (for Andrew Stewart's paternal and maternal ancestry):

Andrew Stewart's mother Daphne Bonsor, daughter of the 2nd
Baronet, was widow of Clyde Graham (her brother later married his
sister in 1945) and named her elder son partly after her first
husband. Her brother the 3rd Bt married a Hambro, and her nephew the
current baronet is married to a daughter of the 2nd Baron Killearn
(half-brother of the 3rd Baron whose son has announced his engagement,
and of Jacquetta Countess of St Germans, and another sister. Marques
will be pleased to learn that Sir Nicholas Bonsor has five children -
including two sons and two younger twin daughters (echoing in that
respect the present Marquess of Salisbury).
