Also Ron wrote in a comment that he spent his early youth in La Grande, so the place of birth is credible.
Among scientists, it is usual to refer to sources that have been cited often enough by other scientists. Though, this fact holds the risk that an entire science does never question a false finding - with fatal consequences. For example, it took decades until scientists found out that entire generations of scientists had wrongly assumed that spinach was rich of iron. Seeing how many people who were suffering an iron deficiency pinned their hopes on spinach, this mistake is a tragedy!
On Wikipedia, most authors aren’t even scientists. Well, I admit that Ron’s date of birth is not important for patient treatments, but I mean to say that all these different language versions on Wikipedia could just cite the same (potentially wrong) source.
