Very sad for your whole Family losing your Mum, I don't remember Her and photos from way back then are thin on the ground, I found myself on 2 photos posted on YouTube, Garry Keen has a lot of good photos on his channel and so do many others, it's a bit of a trawl going through these posts but you may get lucky. All the best to you.
RIP Jenifer, from a fellow Northern Soulie.
