I've found a mildly famous Robertson, who's connected to Allan's tree:
Among Archibald Robertson and Janet Moody's children was John Robertson (1788) who married Betsey Morrison. One of their sons was John Wallace Robertson (1825), and he married a shipowner's daughter named Catherine Barr Thompson. They had 4 children:
John Howard Robertson - b. 20 Jul 1864, Glasgow
Henry Wallace Robertson - b. 27 Jan 1866, Row, Dunbarton
Margaret Christina Robertson - b. 18 Jan 1868, Row, Dunbarton
Archibald Aeneas Robertson - b. 3 Jul 1870, Row, Dunbarton
Archibald Aeneas was ordained in the Church of Scotland, and became the first person to climb all the Scottish mountains over 3,000' high - commonly called the Munros, after Sir Hugh Munro, who catalogued them. He was also a keen photographer, and carted his heavy camera and equipment up peaks in Scotland and Europe.
Quite a few hits on Google (also with spelling Eneas), inc.
