Thank you so much Rootschatters for all your prompt and helpful replies. Like Huckleberry, I was convinced I'd previously found addresses via enumerators' notes but then doubted my memory when I weas unable to find them.
Thanks to you all I have discovered the street and address I was searching for. I put Widnes in the 'born' box and Grenfell St in the 'lived' box, which worked, and then moved Widnes to the 'key word' box, which also worked. I just have to try to remember the the hints and tips next time I need to find a specific address.
