A possibility for what happened to Catharine Quayle dau of Philip Quayle & Isabella Kermeen [bapt Maughold 23 Nov.1817] and her two children, is that she married John Corkill in Ramsey on 18 Dec.1858. The marriage register would give her father's name and occupation to confirm this.

However this John Corkill may not be the "J" who was Ann Jane's father, although he looks like Maria's.
