I've lurked on this site before but this is my first time posting a reply. I was tempted to come out of lurking to post here because the names/ancestors you posted are similar to mine - except my g-g-grandmother was named
Pauline Greenburg instead of Ginsburg!
Malka is a female Hebrew name. So in that example, I wonder if it's mistakenly entered as a brother when it was really a younger sister.
Juda being abbreviated as I. was because they pronounced
Juda as "
Yuda" - being Eastern European, the J would not be pronounced as in English.
Finally, I wanted to add that, in relation to your earlier linked post, Perl is a Yiddish name and not a Hebrew one. I know this because my mother's name is Paulee and she was always told as a child that her Hebrew name was Perl - until it came time for her bat mitzvah and they told her that Perl was not a Hebrew name, and she had to take Penina, which she still complains about to this day! However, I thought that was interesting because it's another example of Perl and the "
Paula" family of names being linked in a Jewish woman.
Hope this helps :)
