The trust officer had a big task ahead of her. Margaret Chappelle, an Edmonton artist and activist, had died a few months earlier, on June 29, 1992 — with no apparent heirs. Her husband, a local doctor, had passed four years earlier and the couple didn’t have any children or other close family. After several months passed and no will turned up, trust officer Ellen Armstrong was sent to search the 1.2-hectare Grovenor estate at 146 Street and Stony Plain Road to find one.
