Similar claims of death certificates being manipulated to increase the number of deaths can be found across Facebook.
These are often woven into conspiracy theories about government control and forced vaccination.
The allegations tend to be attributed to a friend or relative, usually anonymous, but sometimes named, as in the case of "Uncle David".
This kind of misinformation is particularly difficult for fact-checkers and social media companies to fight, because it is impossible to know the exact circumstances of each death.
"When you don't know who the source really is, it becomes much more difficult to check whether it is true or false" says Full Fact fact verification website. "If there is no named source for the information, think twice before sharing it."
But we know that the woman in these photos says she doesn't have an Uncle David and didn't say the words that were attributed to her and that she shared tens of thousands of times.
"It makes me laugh that people are so pathetic that they need to use other people's photos," says Sarah-Louise Cooper.
BuzzFeed News verified his identity in a video call, in which he showed his distinctive tattoos, in addition to a springer spaniel named Bailey, who appears in one of the profile photos used in the “Sara Faith” account.
