Couldn't find an obituary notice for James or Orpha in either the Vancouver Sun or Vancouver Province newspapers. The Vancouver Province carried a small piece on James on December 28, 1940. You probably have this information already but I copied it just in case:
"DEATH CLAIMS FORMER CHIEF
James Anderson, former Chief Constable of Vancouver, and one of the best known law enforcement officers in the province, died in General Hospital at 8:45 p.m. Friday.
Death resulted from injuries received in a fall on a downtown street on Wednesday.
Anderson was Chief Constable in 1921 and was retired in 1929, at which time he held the rank of Inspector.
The late officer's career was a varied one. Born in Banffshire, Scotland, in 1867 he went to the United States in 1889 and worked at this trade as a stonecutter for some years. Later, reaching Victoria, he worked on the construction of the Parliament Buildings, and it was while there he came under the notice of the Governor-General Lord Aberdeen. Hearing of his prowess as a piper, the Governor-General offered Mr. Anderson the post of staff-sergeant and piper in his retinue.
After occupying that post for some years he joined a theatrical company, later coming to Vancouver. An excursion to the Yukon followed, but he remained there only a brief period, coming back to Vancouver. He joined the police force as a patrolman on March 1, 1903, under the chieftainship of Chief Samuel North.
BECAME DETECTIVE
Two years later he was appointed to the detective staff, and in company with other members of the plain clothes force, was instrumental in bringing to book numbers of criminals who had come to Vancouver with the idea of plying their trade here.
In 1908 the criminal records department was founded and Inspector Anderson was placed in charge. A close student of the Bertillon system of finger-printing, he built up a bureau of identification which is considered today one of the most complete records on the Pacific Coast.
His meritorious work placed him in line for yet higher promotion and in 1920 he succeeded Chief W. McRae as Chief of Police, a post which he retained until January, 1924. He was then retired back to the identification bureau as Inspector, being followed as Chief by H.W. Long."
