Aron, Kahn, Levy, Markowitz, Offer, Simon
I am searching for information on these 6 families: Aron, Kahn, Levy, Markowitz, Offer, and Simon. The earliest information I have is 1872 and Aron and Kahn came from Germany, Levy, Markowitz, Offer, and Simon were from Russia.
I am specifically looking for information on Berthold Aron, Selma Kahn, Sigmund David Levy, Adolph Markowitz, Henrietta Offer, and Elinorah Simon. Any help would be welcomed and appreciated.
