Regarding
Rabbenu Eliezer ben Nassan, REBAN
You have information in his profile, and the ozar hachochma website also has a lot of information about him.
I should note that lately, many people set up trees parallel to the general tree and at the point where there is no locked master profile they connect the parallel tree to the general tree and cause damage to the general tree (especially because the information they are writing is incorrect),
Haim Wartski, HaCohen just notify a curator when you see someone trying to circumvent the locked master profiles. Thanks.
