Thank you so much for your reply. I had tried so many variations on the name Kelly but never thought of trying Kibby. This could be a breakthrough. My grandfather lost his mother who died on a voyage home from India; that is why the sons were put into a boarding school. The Harris family seems to fit the bill. My grandfather's mother Mary Elizabeth (Powditch) Kelly had a sister Ann Mary Powditch who married Thomas Gurney Harris. Wills, Norfolk would have been in fact Wells-next-the Sea where the Powditch family lived. Presumably when his mother died and when he left school, my grandfather went to live with his aunt in Hackney. Although not technically so, he was a sort of stepson. Every fact ties in except the date of birth of Ann Mary who was born 3rd March 1835 which would have made her 46 in 1881. I guess this could have been a transcription error.
