It is with deep sadness that we announce the passing of Delacourt Rivers (1901-2026), younger brother of our founder Charles River (he changed his name to distance himself from his brother's deeds in the 1960s).
"he changed his name to distance himself from his brother's deeds"
Observant people will note the use of the ambiguous pronoun here. The truth, of course, is that both brothers had deeds which necessitated the other changing their name.
