I can''t find anything on the history of the company, can you tell about when it was estabolished? As for the logo, I have an idea, it may be obvious, but you said that his name was Bird, well crows are birds, I believe that maybe he was refering to himself, his wife, and son. Or if he had 2 brothers that were partners. They would be "three crows".
Just a thought.
Again, I 't expect much info, but whatever you have is
