OK, sorry about that. If this comes out condescending its not meant to be. The Mormons, Church of the Latterday Saints (LDS) have a genealogy site called familysearch. You don't need to be a member. Once on the site look in the ribbon across the page top, one choice shown there should be Beta. Its a new thing they are trying. Just use the serach boxes as labelled and you ought to be able to verify what I said about the brothers and sisters. If all is as I imagine Mary Ann and John Henry were siblings. Making you a distant cousin to my wife, who was born a Hessing. I know what you mean about fits and starts. The LDS have the records from the Three Presidencies in India. I can order them in to look at in Elgin but they want £17 odd to order each one, but compared to a stay in London and using the India Collection at the British Library its cheap. Incidentally the BL hold images of Col JW and his son George W. Aside from the Tomb at Agra they had a very Jane Austen style house on the banks of the Ganges at Dinapore near Patna.
