Fr. Gregory Chomicky was one of the first Ukrainian Orthodox clergymen in the United States. This collection houses material that documents his ministry as a clergyman, both as a parish priest and as a member of the leadership of the Ukrainian Orthodox Church in America and the Ukrainian Orthodox Church of the USA. It also documents his personal and family life as well as parish and Ukrainian American community activities.

This collection contains six volumes of diaries from the 1940s and '50s, official and legal documents, correspondence, writings on Kuban' history, and photographs.
