Hi Des, When Marie & I researched for our calendar, Mayors of Toowoomba: From Township to City 1861-1904, we found that George Thorn had been born 3 Sept 1852 at Ipswich. His father was Superintendant of the Penal Station at Limestone Hill in 1838, having worked previously for Sir Ricahrd Bourke, Governor of NSW. I'll have to send you the full entry. Cheers Marionne (Diggles)
