Judy — I'm working on it, but I can't actually find any connection between your Inglises and the Inglis family at Chhatak and in the Khasi Hills. According to his 1850 will, George Inglis of Chhatak (born c. 1774, father of Harry Inglis) had 8 children — Harry, John, George, Jane, Elizabeth, Sarah and Mary Ann — but no William, who as a contemporary was the father of your George.
