Sorry to not come back to you, I've been out of the country since the 21st July.
Philip and Elizabeth (nee Quilliam) Camaish appears tp have had at least 13 children. My great grandfather Archibald Benjamin (born 1849 at Patrick) was the eldest and your Julia Jane (born 1865) appears to have been the 8th child. Philip's parents were Philip and Christian Teare. Elizabeth's parents were Robert Quilliam and Elenor Quayle.
I have a copy of the Letters of Administration for Elizabeth's estate where Julia Cain is mentioned as being given notice. I also have a copy of the joint will of Philip and Christan which made Christian the executrix of Philip's estate when he died first.
I can let you have copies if you wish.
Yours Alan
