Hi
More about reliability of sources than the apecific topic. Wikitree tends to be more reliable that eg Ancestry, as you have to have at least 1 source of evidence to enter a profile, and other people can and do make/suggest chnages if it look like it doesn't"stack up" Find a Grave is variable - it's the boigraphy details and sometimes inter-linking of grave memorials to other family members that can be dodgy. I've taken to suggesting bio details where I know those to be accurate to memorials with no bios or changing those which I know are in accurate.
