I have struggled finding any information on my great grandfather, but I did manage to find a Form 548 from 1937. He emigrated from Russia or Romania in the late 1800's, coming first to New York through Ellis Island (so I'm told - no validation on this), then moving to Montreal, Quebec between 1901 and 1903. Upon arriving to the US, he changes his name to Hyman Breitman. I was thrilled to find the Form 548 from 1937 was cross referenced to a Form 548 for Avrum Haim Mutelmaher (alluding to more details) and was hoping to find it and view the details on it, but I have not been able to locate it anywhere. If anyone has any thoughts on where I might try looking, I would be grateful as I have spent countless hours looking and have hit a wall.
