Your cousin Dick Orkin-13 died after his DNA test existed. I am referring to people who died before the DNA test existed. Their profile says they took the DNA test. However someone else has added a DNA test of someone else to their profile.

I had my step father do a AncestryDNA test in 2018 and we got him set up on GEDmatch. He was born in Bristol, UK in 1926. Sadly he passed this spring at the age of 93 but all his DNA test info is on his profile - https://www.wikitree.com/wiki/Marsh-7273
His GEDmatch ID is A196478
I manage his ancestry data - Ancestry member ID britdane2
His Grandparents and year of birth's are:
Peter how do you account for folks who have provided things with possble dna like hair brushes, tooth brushes etc. Some labs are doing autosomal from such items and it does not matter how long a person has been dead?
