Thanks, Private User and Erica Howton.
That must be frustrating that other sites have actually recorded your mother's death, Leanne!
Yes, I would go about contacting them had I access, but unfortunately cannot. I don't know how MH works - whether they get Smart Match prompts and look at Geni profiles as well?
True, Erica, and I try to always post links to sources or at least show where I've sourced my info, and don't take much at face value these days. (This has been a learning process of course and we all get better at sourcing good info!) I'm currently a short-term member of Ancestry and have managed to convince a couple of people of their errors by showing them my Geni profiles with the sources.
I did write fairly clear notes on all of the Geni profiles concerned but perhaps I'll go back to it and add more when I have time to dig up my old notes. (I'm now in the middle of another muddle on the different branch I've been working on, which I'll probably have to post on shortly...)
