Thanks peeps; bit more to work on now.
Wonder if the family member bit could be, say, last two letters of first word and first two letters of second word?
Don't really get it Cashier. I saw for the answer of Minnie it as the daughter-in-law but no idea how to get it! Think I will stick to the straightforward crosswords!
Thank you everybody for your interest, I was able to speak to the person who set the quiz and he inferred the answer may be a song, although perhaps I misunderstood. The only other 4 letter members I can come up with are actually 3 letters with an apostrophe i.e son's, mum's or dad's. I shall keep ploughing on.
