I have recently subscribed to Ancestry, so I am rather new to this.
My father's family, also Tom, came from Warsaw, which was part of Russia. They must have come over to the UK around 1890 and they obtained UK citizenship in 1896.
My grandfather was born in Warsaw in 1880 and I have managed to track members of a few generations of his family.Feel free to look at my family tree.
If Edward was born in Warsaw then there may be a link.
I don't know whether you have done any research on the following site
http://www.jewishgen.org/ as I have managed to track some useful information.
The problem that I am encountering is that there can be different variations of name ie Jewish spelling which makes things difficult.
Let me know how you get on as I am keen to find out whether there are any other Toms around.
All the best
David Tom
