John Alexander Paul Macgregor

John Paul's mother was Drummond Mary, only daughter of Duncan Murray or Macgregor, chief of clan Gregor.

[1] After Lachlan Paul's death, his widow married John Macgregor (died 1847 aged 83), a banker of Edinburgh.

His maternal grandfather, Duncan, was reportedly wounded in the Battle of Prestonpans in 1745 while fighting for the Jacobites;[2][6] Duncan's brother, Evan, also fought with him, and Evan's son John was an officer in the East India Company, became chief of Clan Gregor and a baronet, and served as Military Auditor-General in Bengal.

[3] The practice of appointing young sons of officers to this rank was introduced by the East India Company in 1770 to recognise loyal service.

[9] Macgregor was enlisted as a full cadet in 1795 and arrived in India on 4 February 1797; he was appointed an Ensign on 15 October 1797 and a Lieutenant fifteen days later.

The following June he was attached to the 1st Begal European Regiment and fought with them in the Fourth Mysore War (1798–99), including action at Malavelly and Seringapatam.

He served in the Northern Circars in 1800, moved over to the 1st Battalion 2nd Native Infantry in 1801 and saw action with them at the Battle of Delhi in 1803, part of the Second Anglo-Maratha War.
