Private User are you saying "not even close" to:
Marianna Speijer, daughter of Samuel Speijer Spijer and Vrouwtje Speijer
being a match to
Marianna Samuel Speijer, daughter of Samuel Hartog / Hirsch (Spijer) Speijer and Vrouwtje Salomon / Zelig Zilver Hammelburg
?? Those names are nearly identical. Yes, the locations differ; we do not currently take that into account. The dates differ but still overlap; we only reject matches when there is no overlap between the two profiles' lifespans.
As for the Geni user, we do not automatically assume that makes them contemporary because plenty of people try to create a tree on Geni as Queen Elizabeth or Charlemagne or King John. We need those matches to show up, so we can stop them.
