looked at my copy of 1779 bk1 + bk2 presentments for Marown - in 1st book noted that Jane Quine lately come into parish but she doesn't name father + is set up for an appearance in court - bk2 notes she affiliated on Wm Cottier now in court (but gives no other info re Wm)
you can try to get a copy of the 2nd cas deed from museum library (or wait until I'm back mid August probably) - it may give additional info re the robert corlett
