No. People only stand on that spot once a year and anyway the house is less than ten years old.
I don't know how long the very old floorboards that you are thinking of have been there but much, much longer - possibly even before 1819 if you look at the sixth post at http://www.froots.net/phpBB2/viewtopic.php?t=5465.

Thinking back before 1819, Will.... do you remember the days when that young Corsican used to come and do floor spots in that room singing songs telling us how he was going to change Europe? I think it was his lines -

His men in thousands then did rise,
To conquer Moscow by surprise,
He led his troops across the Alps
Oppress'd by frost and snow,

- that first caused the floorboards to squeak.
