B H Hossack was born on the island of Stronsay, Orkney in 1835 the son of Hugh Hossack and Betsy Davidson. He had 3 brothers Robert B 1826, Charles B 1828 and John B 1830. There was also another Buckham born in 1833 who must have died as an infant. By the time he was 5 he was living at East Road, Kirkwall with his mother, Charles and John. No mention of his father or his brother Robert. He was a teacher in Edinburgh when he married Sibbla Monteith and they must have moved to Orkney not long after as they are in the 1891 and 1901 census at the house which he built, Craigiefield, on the outskirts of Kirkwall. He was the author of "Kirkwall in the Orkneys" which is available to read online at

I don't think the couple had any family and the witness on his death certificate was his cousin William B H Davidson who lived at Viewforth, Kirkwall. He was a Justice of the Peace, a member of Orkney County Council and I believe he is commemorated in a stained glass window in St Magnus Cathedral. I hope this is of some help.
