I don't know if it is a general English thing, or just a Northwest thing, but in Wigan everyone refers to family members as 'our' Ian or 'our' kid, etc.
Of course, when I first came over I didn't know this - and with the way my husband's family pronounced their 'our' I kept thinking they were calling his brother 'HOWARD' John rather than 'OUR' John... I just didn't get it. I actually had to ask my husband if his brother's name was just John or Howard John like his parent's say...
He still laughs at me about it.
