Ellerman Family Genealogy Forum
I just returned from a "fact-finding" trip to Germany and noticed your posting. I discovered a couple of Ellermann relations in my family tree you might be interested in.
The place you wrote as "Herfordt" is most likely the town or district of Herford in Nordrhein-Westfalen, (western part of Germany), on the border with Lower Saxony. Closest major city is Bielefeld. Herford is both the name of a city as well as a district or parish, so your Ellermann may have come from a small village in the district of Herford, as mine did, instead of from the city.
One of my ancestors, Friedrich Wilhelm STORCK, married Catharine Marie Louise SCHLUTER in 1841 in the town of Enger, district of Herford. Catherine was the widow of Hermann Heinrich ELLERMANN, born 1804 in the tiny village of Besenkamp, where he owned a farm. Besenkamp is too small to have it's own church, so christenings, marriages and burials were performed in nearby Enger. As is with German custom, my Storck ancestor took over the farm and used the Ellermann name in official records. The inheritor of a large farm normally kept the name of the original owner, some of my other ancestors in the same situation even naming their sons or daughters after the previous landowner, (making everything quite confusing!). All of these people I've listed were born and died in Germany and I don't have any of the other Ellermann children, if there were any, only Hermann Heinrich's father, Caspar Heinrich. My line is from one of Friedrich Storck's sons who came to America (Wisconsin) in 1873. The original church records of the city of Herford, Enger and the surrounding countryside are held at the Nordrhein-Westfalen Staatsarchiv in Detmold (see http://www.archive.nrw.de/ and go to the map), but you'd have to hire someone to do the research. Although the website is in German, you can dump it into a free translator like Babelfish. Hope this helps.
