Hi, Im tryig to trace my family tree and wonder if anyone out there can help me.

I am from the UK and my Grandfather was Max Rogoff (born circa 1900)

He had 7 brothers and sisters, Jack, Phillip,Charlie,Isaac,Anna,Kay and Eva.

The reason I am posting on here is because I know that at some stage after arriving from Poland, JACK emmigrated to the USA...but after that I don't know any more!

Can any one help? Their Parents were Brenda and Samual Rogoff (but I think it was originally something like Rogove, but was changed at some stage)

Many thanks
Seth Rogoff
