Self-evidently I am not my grandpa

Lets take this "truth":

Quine explains, “No bachelor is married,” where

the meaning of the word ‘bachelor’ is synonymous
with the meaning of the word ‘unmarried.’ However,
we can make this kind of analytic claim into a
logical truth (as defined above) by replacing
‘bachelor’ with its synonym, that is, ‘unmarried man,’
to get “No unmarried man is married,” which is an
instance of No not-X is X.
Then examine this "truth":
Lets say you build a Prolog family database and
make definitions for father, grand-father etc..
Will this Prolog family database exclude:
"Im my own grandpa"
