The picture shows the man dancing with the girl as the cathedral stands proudly in the background.
Although Brooke said she's unsure whether they are father and daughter.
She later added: "I do not know for sure if it was a dad and daughter, it’s simply the dynamic I observed from them while debating on interrupting this moment.
"It may be an uncle, brother, friend, who knows until we find them.
"It was taken at 5:57 local time."
Brooke told the BBC: "We watched in shock and heartbreak with the rest of Paris."
Other Twitter users have described Brooke's photo as "historic".
Michelle Bhasin commented: "This is going to become THAT photo."
