sterling silver miniature Alaska Russian churches

I bought these mini Russian churches in the late 1980s, early 90s. All the churches are signed by the artist, John Tennant. The churches are replicas of the Russian churches built in Alaska. The one with the tallest steeple is in Sitka, Alaska, my home. I'd like to find more information on John Tennant the Alaskan artist, but cannot find anything on the internet. I had a brochure but have lost it along the way. Any help would be appreciated. Each church is cast in silver, numbered as a set (7) and signed by John Tennant.
