Shalom, 

This tree on Geni details the following connection of certain branches of the Heilprin family to the Maharshal: 

I can prove up until the red line. 

I would be most grateful if someone could please provide me with any sources that show the connections from Rabbi Yisrael Charif to the Maharshal. If it is known, I would be most interested in the earliest source. 

If another connection is known, I would also be interested. 

Thank you very much indeed. 

Kol tuv,
