The Admor Alesk was R. Isaac Ashkenazi (adopting his wife's name),
Admur Olesko-Stanislawow, born in 1865 and perished in the Holocaust
in 1942, son of R. Jacob Zvi Hirsch Weilziker (Weliczker/Welitchker)
of Sokol.

one of Isaac's daughters married Yekutiel Zalman Weber - which is what
I am trying to find out

These are the daughters I have -

Chaya Rosa, born in Olesko in 1879.

Esther Reizel, born in Olesko in 1882.

Rachel, born and died in Stanislawow at three months in 1901.Maybe
there were others.
