Alaska Obituary Records
Alaska obituaries can be a bit hard to come by as the state is sparsely populated and comprehensive databases are few and far between. An excellent place to start is with the Anchorage Newspapers Search Engine that is located on the website for the Anchorage Municipal Library. This is a massive database that not only covers most of the cities, but many of the rural areas, as well. Currently, the database only goes back to 1981, but there is an intention to expand it further back so that more and more listings will be searchable.
At the time of this writing, it appears that you do need some kind of library card or permission, so you may want to contact the library to see how those outside of the state can access Alaska obituary records. In addition, you may also want to consider searching British Columbia & Yukon, Canada records for the person you are looking for, as the border between Canada and the United States is poorly patrolled, especially back in the distant past.
