I've atempted to find some more information on this woman's case but I haven't had luck, there is only the post on pinterest. I am not sure even if the woman is still alive, she would be now 102 years old. Anyways, the claim was made in 2011 and nothing else has appeared after all. The post doesn't mention any DNA test, so I think none was made at least when she made her claim. I am not surprised, only very few claimants dare to take DNA tests.
