Several Wartski trees

From the first day I started dealing with my roots and my family tree, I tried my best to find information about the Hachoen Wartski family
I did my best to find information ... all the family members I know living today, do not know details to give me.
About 3 years ago, I found in Australia a man I believe is my grandfather's nephew

Unfortunately, I did not get a response from them (although I tried to contact them several times)

The information I know with absolute certainty (including verification by Naftali Wakstein): My grandfather is a descendant of the Maharal's from Prague son (through his grandmother Ryfka Wartski nee Krol-berle "s),Through her he is also a descendant of Saul Whal

Following information that I found peace regarding the Hachoen Wartski family, I turned to Naftali Wakstein and we checked together and found that Rabbi Ephraim Fischel HaCohen

Following information I found yesterday about the Hachoen Wartski family ,I turned to Naftali Wakstein and we checked together and found that Rabbi Ephraim Fishel HaCohen

Efraim אפרים Fishel פישל kohn הכהן

is probably my great grandfather 4 or 5
And another thing, it seems to me that all members of the Wartski Hachoen family are relatives and we all have a common ancestor.
.
If there is anyone here who belongs to the wartski family or who has information and can enlighten our eyes, I would be very, very happy and thank him alot
