Germany/Prussia to England immigration

[dxbudgie]

I have 2 brothers who moved from Hanover or Hamburg to England sometime in the mid to late 1800's.  They married two sisters in Liverpool then both families moved to the US.  I have been able to find their families in NY/NJ without problem and I have their marriage certificates from Liverpool.  I am at a loss as to where to begin to find their German roots.

Henry (Presumably Heinrich) Tavis (Teves) B. 1838 Hamburg 
Married Catherine Tate 21 June 1863 Liverpool
Father on marriage cert is listed as John Frederick Tavis
Found in 1870 New Jersey Census with wife and 3 children.  The youngest age 2 listed as being born in England.

Johann Teves (Tavis)  B. 1837 in either Hanover or Hamburg
Married Jane Tate 16 Oct 1864 Liverpool
Father interestingly listed as Frederick Teves.  Not sure why Henry decided to make his name more English but Johann changed to John Tavis after moving to USA.
Also found in 1870 NJ census with wife and 2 children. Youngest age 1 born in England.  Both families lived in same building together.

I have near nothing on the brothers or their parents aside from that information and I'm not really sure where to begin.  I have no information as to how/why/when they moved to Liverpool.  Any ideas would be appreciated!

Hello,
I too have a similar problem!.
My greatgrandfather, born in Hamburg in 1850, moved to Liverpool, sometime around 1860/70, and married a Liverpool girl in 1879. They had quite a large family, at least six that survived. They lived in Toxteth Park, but my grandfather, Emil David Engelbrecht, never put his name to anything and made it quite difficult to trace him. I cannot find any reference to his birth in Hamburg, most of the records I believe were destroyed by those British bombing raids sometime during the 39/45 conflict. He changed his name to Engelbert and died in Pontefract in 1939.

Regards

Frederick
