I have been asked to provide any additional information I might have on these individuals.
I have only the following dates/locations that seem to be a consensus:
Pinchas Halevi Horowitz b possibly 1550-d. 4 Jan 1618 Krakow Poland
Miriam Beyla Isserles d. 29 Aug 1617 Krakow Poland (I believe her to be the daughter of Yisrael iser Isserles of Krakow and wife
Dina Malka Shrentzels)
In particular, I am trying to find a complete list of their children and see if Yakov Yukil Halevi Horowitz who d. 1630 Vienna Austria is their son.
Regards and thanks,
