EG died in 2009. There probably had been a strong family and/or business relationship. Google around and you'll find that WM appears to have been deeply engaged in numerous wildlife and other animal rescue initiatives.

Oh my, oh my, fellow sleuthers, lookie what I found. Apparently WM and/or DM were or are the executor of the EG estate.
The telephone number provided at the above addy provides "
Her EG Animal Welfare Foundation was established to offer help to injured or abandoned urban wildlife. Members of the G and J Family are invited to call Elizabeth's executor at 416-695-2521."
