Query on children

I have been asked by the family to raise this question

Private and Private appear to be the same however one has children that possibly in the incorrect place (are perhaps grandchildren rather than children)

https://billiongraves.com/grave/Yvonne-June-Lovell/28868736?referre... lists the children as David, Carol, Greg, Cheryle, Garry, Rob, Karen, Wayne, Micky, Judy, Leon, Pam, Rod & Jill

The information I am receiving is that these 2 are not her children but her grandchildren

• Private
• Private

Can anyone provide any information on these 2 children?
