I became involved in 2011, the DNA was flawed, we were able to get mtDNA but the matches were so distant (above 10 generations) it was impossible to get anything from it.
Since then, Hal and I have been working on this case daily to get Miss X identified. We've been down so many dead end roads you wouldn't even believe it. We came across some additional material that we were able to extract DNA from at the end of 2020 and although the chances of it being viable were slim, we gave it a go and it worked. The files were transcribed and uploaded to Gedmatch. We knew who she was in 2020, we had photographs, details of how she ended up on the side of Porter Road, everything... but we couldn't prove she was Patra legally as surviving adopted family were small cousins when she disappeared and her biological half family didn't know what she looked like! It has been a long, slow, legal slog to prove that Miss X is Patra, but we got there in the end!
