Websleuths is victim-friendly. Cecile’s family are victims so there should be none of that here, but if you see something like that please use the report button. Regarding the family providing a DNA sample… it’s something that only has to be done once. Why wouldn’t they want to provide that for comparison with future possible matches? (Genuine question, I’m not trying to be snarky) Maybe they thought it’s something they would need to do each time a possible match was found?
