I live in Vancouver Canada, my house was built in the 1950's and the basement has the floor joists of the kitchen [above it] exposed.

At that time forestry here was felling massive ancient trees. I'm curious how precisely I can establish a maximum age of the trees felled.

Obviously I could count the rings visible on the joists and subtract that number from 1950, but not having the tree's full diameter limits measurement. I understand it's possible to compare relative ring sizes with existing [cross referenced] data sets to date timber.

Does anyone have any experience doing this or able to point me in the right direction? Any resources I'm unlikely to find on Google?

You would want to send out a sample and have professionals reference their data. I guess you could try and get their data(maybe a university researcher would be favorable) and do the cross referencing yourself, but dear God that would be tedious.
