By the Grace of G- d20th of Sivan, 5714Brooklyn , N.Y.
Sholom uBrocho :
I received your letter in which you write that a proposition has been made concerning a Shiduch for your other sister with the brother of the bridegroom of your first sister, and the question is whether two sisters may be married to two brothers.
In reply, I want to tell you that if your sisters will take upon themselves to conduct their homes in accordance with the requirements of the Torah, observing Taharas Hamishpocho, Kashrus, Shabbos, etc., and if they will not live in the same town,1 it will be quite in order,2 and may G-d help that it should be b'shoo toivo umutzlachas.
With blessing,
By Nissan Mindel
Secretary
