That's something else I didn't know - thanks Frances.

I have found something but I can't read the name properly.
In 1881 the family were living at Kerroodhoo, Patrick.with Margaret's mother Ann Corris.
But in 1891 they are in Brunswick Rd, douglas where Mgt is married age 45. Catherine 20, John 18 Edith [visitor] and someone Cowin the right age [visitor] - looks like Will but middle bit doesn't look anything like Quayle.
