I'm sure somehow all Lowenthals are related. My grandfather's sister married Jonasz Lowenthal, lived in Boryislaw and had 2 daughters together, Auda & Lotken. I haven't been able to find out any info about them since 1939. My Aunt was Feige Cirl Kreisberg Heimberg Lowenthal. Maybe you or someone else can put the pieces together.
