Have to given any thought to Ursula's (Merrin) mother could be the counterpart to the wife of Posiden from the myth, Amphitrite, the sea-goddess of salt-water. And that Ursula is a goddess in herself, maybe a minor one (maybe after transforming she became like the sea/ocean version Hecate the goddess of earthly magic), and she is simply named after a more ancient goddess Ursula which like in the show she made herself more like that Ursula (ie. changing herself into a ceacelia and learning the art of magic) to make herself stronger and protect herself.

Also, I did like the theory of other Ursula (Yvette) being in a slumber when Regina invoked her appearance and Ursula called her out on it. But it also begs to differ why wouldn't she call out the other Ursula (Merrin) impersonating her too. So maybe that Ursula has long since past and is now only a title or myth to the mermaids now and that it was Ursula (Merrin) who called out Regina on her impersonation and maybe later after getting know each other it defrosted their relationship and are now fremenies. The reason I think this could be possibly is because of the ever continous flashbacks we get of everyones relationships and storylines changing what we thought we knew of thier backstories which makes them more richer and colourful. Also Merrin is still billed for several more episodes inculding "Best Laid Plans" and "Lily" in which more about her past could be revealed.
