As far as I can find out he wrote 3 books, Tales the Totem Poles Tell, published 1946,
Fir Forst Fun pub 1947
Teddy,Dappy & Joe, pub 1947
Last two are for sale on the net for $50.00 each.
Also drew some maps," Rawhide Maps" of Stanley Park.
He was born 1908 but haven't found a death for him yet.
His second name may be Wallace.
Go to www.islandregister.com/weatherby.html
Weatherby genealogy is there.
Says he was born Hugh Wallace Weatherby, Dec 1908 (same date as his bio for the books), married Lucretia Weatherby. That would be your Crete. Maybe he is still alive.
His parents were Hiram Winfred Weatherby and Elizabeth Kirwin.
I couldn't find anything re his death on BC Archives. His father died in Haney, BC in 1945 or 1949.
