I'm continuing a thread started under the record of R' Benjamin Braude, A.B.D. Grodno who was, at that time, listed as the father of Slawa Ludwinowska. Slawa's mother was listed as Rachel Broide at the time listed as Benjamin's first wife. As of 7-29-20, as you can see, Slawa's parents are now listed as Sender / Alexander Broide (Benjamin's brother) and Rachel Mayer. There'd been some discussion under Benjamin's entry of available records and narratives indicated by different family trees that linked Slawa either to Icko Brodowicz or Benjamin. I don't understand the change attaching Slawa to Sender.
In separate entries, I will summarize the earlier discussion.
