Knowledge on East European migration in 1891

The people I knew with that name were German immigrants to Central Texas. It appears to be a Northern German name. There was a huge immigration out of Europe and to the U.S. and Canada in the late 1800s. I'm not an expert on German but I can tell you that 3 million Jews out of Russia left. I think that this was true also of ethnic Poles. Ludtke could be a German ethnic name from Eastern Europe since a number had settled further east over the past century.

1,445,181 Germans emigrated between 1880 - 89, And 579,072 between 1890 - 99.

Ashley is good on European emigration. For some countries, more people emigrated in the late 19th century than live in those countries today.
