Please be advised, the current GENI arrangement of Sirkis spouses differs considerably from Jacobi. Here is how Jacobi interprets the evidence: 1) Rivkah Reikle Sirkis-Segal, [TuZ 2nd wife] isn't involved with either Shmuel Tzvi Hirsh Sirkis or Rabbi David Halevi Segal, the "Turei Zahav" (Taz) (and I don't know anything about whether she married and if so, to whom), 2) instead, Rivka Sirkes is made the spouse of Shmuel Zvi-Hirsch Sirkes, of Pińczów (and is not the spouse of R' Aryey Leib Sirkin, A.B.D. Cracow and Brisk as currently appears on GENI), and when her husband died she became the spouse of Rabbi David Halevi Segal, the "Turei Zahav" (Taz) who only ever had one spouse, 3) meanwhile, Rivka Segal, [Tu"z 1st wife, Bach dau.] was never the spouse of ttps://www.geni.com/people/Rabbi-David-Halevi-Segal-the-Turei-Zahav-Taz/49..., and instead is the spouse of Jakob Ish Tam ben Elhanan Jacobi, p259-60, Vol. 1
