The family tree,  as linked to above, was made by Rev. Douglas Pankhurst, Great Grandson of George Spencer. The reverend's information was received on the occasion of personal visits, or in response to letters. The work was completed first between 1946 and 1953, then revised and updated in 1981. The tree has two purposes;
1) to show as accurately as possible the descendants of the seven brothers and 2 sisters who came to Canada in the 1950's,
2) To try to show clearly how the descendants relate to each other.
