Can resist adding another "have you checked?..."
Is there a chance that the deeds were transferred at different times, but
were only filed/registered on the same day? If so, then some of the other things
people have suggested might make more sense.
If the above is true, then in the early body of the deed, it will say...
"Sam...to Bob.... on the 13th of April 1957" but at the end "received
(registered), this day, the 2nd of August, 1962"...
Just a thought.
