If it was "slow moving", that would cross Leonids of the list of possibilities, along with most cometary sources as I said above. Also, for you to
be able to see meteors belonging to a specific shower in the sky, the radiant of
the shower in question has to be close to, or above the horizon where you are. In your case, that does not happen till around 11:30 PM. Before that
you could not have seen any Leonids.
The fact that you saw it near Cassiopeia in it's self is not grounds to dismiss it as not a member of the Leonids shower. A Leonid is not a Leonid
because it is seen in or close to Leo, but because it travels away from the Leonid radiant. Where it starts or ends can help to identify it as
being a Leonid or not, but Leonids can appear almost anywhere in the sky once the Leonid radiant is well above the horizon.
There is a chance that it may have been a Taurid though,
since the radiant is close to the horizon at that time, but it's probably more likely that you saw some random asteroidal material entering the
atmosphere.
Without accurate coordinates of the start/end positions of the meteor, as well as knowing the length and speed, it's hard to identify a meteor with
any real certainty, even if it is a member of a meteor shower. Learning where the radiant is at any given time, and having a knowledge of the
stars/constellations so as you can identify it there and then, or plotting the meteor on a star map is the best way to identify meteors with any
degree of certainty.
