Margot Pels buried in Sweden

At a local grave yard in Lund, Sweden there are graves for refugies from the concentration camps. Most of them came with the so called white busses in 1945. There is a grave that belongs to Margot Pels born in the Netherlands 1909 and she died May 1946.
Since the authorities have planned to take away this grave I would like to examine if there are still relatives in life who are interested in getting information about Margot Pels. I am not quite sure if she was Jewish and if she came with the white busses though.
I am willing to answer your questions and helping you further.
