In all the many sources I have read so far, Rabbi Yekutiel Rappaport was mentioned as the first of the Rappaport family.
I found the book about the Rafaport family (I am attaching a link to the book), and there it is written in the title of the book something different: the first of the Rapaport family is Rabbi Avraham Rafa from the city of Port, and his father was Rabbi Yaakov Hachoen, but a few lines below it says that Rabbi Avraham was the son of Yechiel Cohen Porta , who wrote the book
"חוות יאיר"
I noticed that in the
symbol of the Rapaport family ,there are 2 names: Avraham Menachem son of Yaakov Hachoen
This is the link to the book:

What is the connection between him and Rabbi Yekutiel Rapaport, father and son/something else? Right now, I don't know
If anyone has time to read the book (27 pages), I believe and hope that answers to questions will be found in it, and maybe we can continue the family tree
