This document is a brief registering a claim by Alexander Mackenzie, a soldier in the East India Company, to the title of baronet of Nova Scotia. As the eldest lawful male heir of Sir Kenneth Mackenzie, who received the hereditary title in 1704, Alexander argues he is entitled to the title as the nearest male heir in the lineage. The brief traces Alexander's descent from the original title holder through multiple generations to make his case as the rightful claimant to the baronetcy of Nova Scotia.
