He took the additional name of Glen before that of Coats by Royal Licence when he was created a baronet. The name Glen comes from his mother's family and his first cousin, Matthew Arthur, 1st Baron Glenarthur, likewise added Glen when he was raised to the peerage.
He is buried with his family at the summit of Woodside Cemetery in western Paisley.
Thomas Glen-Coats married Elise Agnes Walker (1855-1910), daughter of Alexander Walker, Esquire, merchant, of Montreal, in 1876. She was identified with Liberal associations and interests in the West of Scotland. Their eldest son was Sir Thomas Glen-Coats, 2nd Baronet, an Olympic sailor. In July 1902, their daughter opened the new sanatorium for consumptives at Athronhill, Scotland. The family donated $10,000 to the London Cancer Research Fund.
