Just noticed that the first post says that "George Hutchison and William GFAF Hutchison both served in the Madras Army"
Allen's Indian Mail (1847) page 595 has some marriage announcements:
"ACTON, Lieut. H. 4th L.C. to Laura A. d. of the late Capt. Hutchison, M.A. at Bangalore, Aug. 3."
That all seems to fit nicely.
