My name is Michael Waas. I saw your posts on Ancestry.com. I would like to hear from you further. One thing that was very poignant that you wrote was the amount of Blumberg's that either converted or grew up believing they were christians: my great-great grandmother used to call herself Mrs. Livingston (her married name was Levenson) and her children celebrated Christmas even though they all carried on being Jewish. I am eagerly looking forward to hearing more.
