I just thought I would share what I found so far regarding the family tree.
So after searching malcolm Ian duncan. His name popped up through house address directory on the public websites. It fitted the description of him being deceased and was living in texas. Kelly’s name was there and there was also a Cheryl Duncan Anders, who Malcolm Duncan had lived with at one point before then moving to live with Kelly. Cheryl seems to be only a few years older than Malcolm. So I was assuming she might be his sister (unsure). I ruled out mother or daughter.
It stated on that site that both Kelly and Cheryl have muitple surnames. Through Facebook I found Kelly and several facebook pages. Also her sisters and some of her children. Only by chance I found in an old post Kelly mentioned the name of her Grandma ( which I have now added to the family tree).
As for Cheryl Duncan Anders she had a facebook family tree details and there was a brother called Cary Anders . His mum is called Connie Delviccio. But she does not have Cheryl down as her daughter on her facebook family tree, only Cary as her son.
So that is all I have found so far. I was not able to trace Cheryl’s grandmother either. Kelly also did mention her mum in an old post but unfrotunately could not see any name. And I could not find any social media page for Malcolm Duncan or him mentioned on his children’s posts except once or twice by Kelly.
Kelly remarried too and that husband also passed away and a public obituary was made by Kelly as well.
