Naomi, I did try to find out for certain, but gave up. Ethel and I used to keep in touch via Skype. She was a very poorly lady, getting on a bit (70+) and her ailments were getting more severe. I worried about her, being a lady living on her own, and mentioned this to her on more than one occasion.
Her contact stopped abruptly and I don't think she would have just left it like that. I hope one day she (or someone else) might prove me wrong, but to be honest I doubt it very much. [:o(
