There are two different Lazar Riesenbachs most likely
Lazar Riesenbach in Mukachevo was married to Matel Riesenbach where he had multiple children
Lazar Riesenbach in Mediesu Auriu and Seini, Maramures, was married to Mali Amalia Riesenbach and had multiple children there.
There is too much overlap between the births of their children in those two different places that they have to be two different people with a similar name... Unless someone comes with a different expanation :)
Also, need to research which one was born and died in Austria (Vienna etc).
