Hello Ingrid I am not a direct relative as far as I know but I have been doing a lot of research on teh Helmke families in America. My ancestor came to America in 1845 to New Braunfels Texas and he came from a villiage of Gross Heins, Kirchlinteln Germany which is about 40 miles from Hamburg. There are a lot of Helmkes in the area of Bremen, Fallingbostel and Hamburg and Rothenburg which are not very far apart in Germany. I am in the process of having a professional researcher reviewing the records of this area. If you could send me information on your family as far back in Germany as you can I may be able to connect the dots if I knew More. Get back to me if your are interested in pursuing the search.
