In addition to the record collections noted for each of the provinces in this series on provincial/territorial record collection, you will find that aboriginal ancestry will require the use of other important, and primarily federal, record collections. If your family has been attached to a particular band in a province, the band office will have records about you and your family. Accessing these records will fall under the policy of the band, but for easier access as most of the 20th century band and federal records will be strictly held, you will need to extend your family’s ancestry back to pre-20th century. Once you have traced your ancestry back to the beginning of the 1900’s, you will find that many of the records relevant to you will be available on microfilm.
