Am unaware of any such testing
Ex-Chmielniks living in UK may be interested to know that a branch of Chmielniks has been located near Haifa in NW Israel, being 2nd and 3rd generations of Holocaust survivors who had been presumed dead.
See family tree as updated by my sister Mira Meshulam.

My oldest best known Freedman link in England is Harris Freedman, my great grandfather. He lived in Benthal Green and he was married twice. I have uploaded the certificates here, see if you can find any known name:

From the first marriage he had one son and from the second he had four, you can see in my tree,
All the family moved from London to Buenos Aires in 1908 and some sons returned to London in 1922.
Harris Freedman was also known as Herman Freedman, his father was Lipman Freedman or Friedman and I think they all arrive to England from Kiev, but I am not sure.
I really don't know if your Freedman branch has any direct link to my branch, but it is funny to find it out.
Regards,
Hernán Freedman
