I like
Sorcha and I love
Sorcha and
Ronan as a sibset!
I prefer SOR-ka for an anglicized prn. but I guess SOR-sha works too (but I might prefer SOR-cha, because then it doesn't remind me so much or
Saoirse). ANyway, I don't like any other spellings. Sorsha and Sorscha look awkward and misspelled to me!
I like
Sorcha Helena best! And
Sorcha Kathleen is good too. I'd like
Sorcha Regan (although I don't like
Reagan with the a for some reason).
Sorcha Aurora is too rhymey, but I wouldn't mind
Sorcha Aurore. I love the "or" sound, and I don't think you can have too many "or"s :P Although having two names with an "or" sound does make the combo a little singsongy.
