I think it's gone.  You only have two members of the 42e59462 uuid
array, and you need at least three.  The others all have 2008 timestamps
so could not have been part of the desired array at any recent date.

Sorry.

You *could* assemble the other array, though, to see what's there:

mdadm -Afv /dev/mdX /dev/sdb1 /dev/sdb4 /dev/sdd

With the failure mode you described, I doubt the series of rebuilds
would have destroyed much.
