And in 1861:
George Gall 59, shepherd, b. Inverarity, Forfarshire
Jean Gall 37, b. Monikie, Forfarshire
Jean Gall 12, b. Carmylie, Forfarshire
William Gall 9, b. Port of Menteith, Perthshire
Ann Gall 6, b. Barry, Forfarshire
Mary Gall 4, b. Barry, Forfarshire
Margaret Gall 2, b. Brechin, Forfarshire
Address: Ibert, Drymen, Stirlingshire
With George's age showing as 59, not sure if this is a transcription error on the index. If not, then the George I posted for 1851 can't be him! Again, the original image would confirm.

Added: SP have him also indexed on the 1861 census as age 59. However, his age at death in Buchanan, Stirling in 1869 is 47....so the 1851 census entry could still be him...
