This may be redundant of source cited but half of my paternal family
lived west of the Rhine and in every case both old patronymic and
new first and last names are listed.
Often first names were changed to more French names, I found this
more common among females.
In some cases the last names were hardly distinguishable as Jewish.
In my Loeb family there were several in the same town who chose
Jakob as a new first name so these Jakob Loebs were followed
by I, II or III to distinguish them.
My great grandfather was known as Jakob Loeb I. As you know, half
the fun is they were written in French using the French Republican calendar.
