Mother of Ponim Meiros Eisenstadt (Dau. Shach sister (Esther? Miriam?), Hacohen) - Was this woman the Shachs sister?

Hi,
Still having trouble with the relationships. If she was the Shach's step-mother-in-law, it's very hard to imagine her also being the Ponim Meirot's mother, remembering that the Ponim Meirot (born 1670) was the grandson of the sister of the Shach (born 1621).

בס"ד
לחותן הש"ך ר' שמעון בנימין וואלף טויבער ולאשתו השניה – אסתר, אחותו של הש"ך, נולדה בת, והיא היתה אמו של
הגאון הגדול בעל הפנים מאירות. דהיינו, שר' יצחק אבי ה"פנים מאירות", נשא את אחות אשתו (שהיא גם בת אחותו) של השך.

Because things are still not quite right on GENI here is a brief summary of the situation. This is a quote from the blogpost summary of Wakstein http://toladot.blogspot.com/2011/04/blog-post_15.html?m=1 :
"Apparently, the aforementioned Rabbi Shimon Wolf had several marriages. A] The first one's name and her father's name are unknown. From this marriage, his daughter was born - the wife of the Shach. B] The second, Mrs. Esther A.H., the sister of the Shach. From this pairing, the mother of the "bright face" was born . C] In a third marriage, he married Martha Bila AH, daughter of Rabbi Hirsch Dahliner." So according to this, Esther was the mother of the mother of Ponim Meiros.

I don't know how Rabbi Yaakov Hirsch Levenshtam, ABD Brisk & Lublin enters the picture, but perhaps he is the father of the first wife of R' Shimon Wolf mentioned above, in which case he would be the Shakh's wife's maternal grandfather.. I have no evidence of this besides the fact that somehow R' YH Levenstam has become the father of wife, Benjamin Zev Wolf Ashkenazi on Geni.

Another possibility on the spouses is that Rabbi Yaakov Hirsch Levenshtam, ABD Brisk & Lublin aka as Lubliner,,is the same as the R' Hirsh Delhiner mentioned above whose daughter was the third spouse of R' Shimon Wolf (but which did not lead to Panim Meiros, nor was married to the Shakh).
