The truth of the bible is in some cases suspect due to erroneous linguistic interpretations by experts who not a good as they claim or biased in favour of a result.

I know for a fact that Cornwall/Somerset had tin mines. So tin merchants are a reasonable assumption. The fact that Joseph of A was a rich tin merchant could be disputed, however on what basis?

The story of of Joseph in Cornwall is a story that persists.
The rest of the story can neither be proved or denied except that it is part of the same narrative.

The source of the genealogy of Joseph of A is noted.

I am stating facts. If the stories are not admissible due their oral nature then neither is the bible for the same reason.
