May 1st, 2020: I have started a ROTHE surname project; please join me in researching this name!
November 11th, 2020: The ROTHE project did not really start as I regret. My health and ability to concentrate on that was not strong enough to follow my aims in this case until now. I hope to get further in the beginning of 2021. Please have a bit pacience with me.
