Marcus Curtius


The Curtius

(alias Curtze - Korte - Kurtz - Kurtze - Kurz & Van Someren alias Van Zomeren families)

Genealogy [Familienforschung] & DNA Website

If you are tracing your ancestors then finding this website could be your lucky day!

Welcome to my website for researching the genealogy of bearers of the surnames Curtius, Curtze, Korte, Kurtz, Kurtze or Kurz and other surname variants; including my own name-changed Van Someren alias Van Zomeren family. For simplicity I am grouping them all under their common Latin version of the surname called Curtius.

The first thing to mention is that this website is generally in English but also occasionally in Dutch or German and other languages depending on the sources being used; so my apologies to all the English, Dutch, French, German, Scandinavian and Slavic language visitors for the general mix of languages being used, but I hope you will understand the content; especially with the 'Translation' aid located on the upper left under the equestrian animation of Marcus Curtius (our 'patron saint'!).

This website will be of interest to those of European ancestry researching the surnames:- Brevis, Coert, Coerts, Coertsen, Coertsz, Coertze, Coort, Cort, Corte, Cortum, Cours, Curti, Curtius, Curtse, Curtze, Curtzius, Koers, Koert, Koerts, Koertse, Koertsen, Koort, Koorts, Koorzen, Kort, Korte, Kortum, Kortüm ("kurz um"), Kortz, Korzer, Kurtz, Kurtze, Kurtzius, Kurz, Kürz(e)l; Lutke; Lutteke; Parvus and also for my own name-changed family of Van Someren alias Van Zomeren who were originally surnamed Kurtze and also were assigned the following Dutch variants: Curtse, Koerts, Coerts, Koers, Coertsen, Cours and Coertsz.

The surname being researched is essentially Germanic e.g. from Germanic language areas of Europe, which include Germany and the greatest historical areas of German settlement and influence e.g. Alsace, Lorraine, Prussia, Silesia, German colonies in eastern Europe etc.; the Low Countries of Belgium, Netherlands, Luxemburg; Switzerland; Austria; Bohemia; the Baltic States and Scandinavia. There are many spelling variations of the surname, but most written formats may also be found using a common Latin version often found in official documents and that is "'Curtius", also "'Parvus" and "Brevit"; therefore I have adopted this Curtius version of the surname as the 'lingua franca' that is common to all; so when I mention "Curtius" I include all the variants; Curtius = {Curtius, Curtze, Korte, Kurtz, Kurtze, Kurz etc.}; welcome to the Curtius website.

Read the following, it is important:

Part of this website is password protected! So that you are restricted from access to the database of information.


Well, I do not want to just give away my years of research without getting something back; that something is not for me, but for the benefit of the Curtius family generally. I want nothing but to expand the Curtius database of knowledge with your help.

To access the database, I want you first to have a Y-DNA test taken through Family Tree DNA (FTDNA). Once you get your Y-DNA results recorded on the FTDNA website along with what you know of your ancestry and where your earliest known Curtius ancestor originated, you will receive the password from me to enter this database, where you can search and copy the information to your hearts content. I hope this will be an incentive to boost the Curtius family Y-DNA research and we can all see how we are genetically related. Getting your Y-DNA tested is something you should really want to do, as it is the most essential contribution to your genealogy! It provides unequivocal proof of your identity and a several thousand year link to your deep ancestry and genetic route to the origin of your existence when life evolved on Earth. The whole purpose of this website is essentially to encourage Curtius, Curtze, Korte, Kurtz, Kurtze or Kurz etc. and Van Someren alias Van Zomeren families around the world to have a Y-DNA test to build up a comprehensive Y-DNA database of the family surname.

Contact me through the Feedback link below. If you cannot communicate in English, I do understand a little Dutch and German and of course my computer translates.

I want this to be a great Curtius family database and with your help I am sure we can make it so.
