We evidently have a problem here, either with the birth year or the marriage date...
https://www.genealogieonline.nl/west-europese-adel/I70565.php seems to indicate she was born 1235. (and married at age 10?!)
there are several elisabeth's see https://gw.geneanet.org/adverschoor?lang=en&pz=ad&nz=versch... and https://gw.geneanet.org/prodigue?n=van+elsloo+van+meurs&oc=&...
the marriagedate is from the mother, not from the child born 1250
I can't merge the profiles, please change as curator.
