Interestingly, Alice Carr, the sister of Emily Carr was the Hennell's nanny, and remained lifelong friends with the family.
He exhibited with the Island Arts & Crafts Society from 1913 to 1917. In the 1917 exhibition Hennell entered a poster into a competition, but did not exhibit.
When World War One broke out, artist & architect William Ridgway Wilson made a partnership with Hennell while Wilson went into the army.
After the war Hennell moved to New York where he continued to work as an architect, and where he died in 1961. Prior to that, Alice Carr commissioned him to design a bridge that was built in Beacon Hill Park in honor of Emily Carr. It was dedicated February 10, 1953.
