I would say that it makes the most sense for Hook to have a background with Ursula as well. But whoever the connection is, the connection most likely occured in the brief time between when Killian took control of the Jolly Roger and when he departed for Neverland (Unless the connection happened IN Neverland).

It is possible that it occurred in the very brief span when Killian returned from Neverland, that was a very short time, and much of it was spent with Regina and Cora. right before the first curse was cast.
