I noticed your willingness to exchange information and am willing to share what I have. I have factual as well as undocumented information on my Riemer line.
I believe all Riemer families originated in Holland because the i before the e indicates the Dutch origin. It appears that my Lutheran ancestors were chased out of Holland and moved to the Dutch colonies of Poland where they were rewarded with free land and farming essentials. They spoke the high German of the Lutheran faith.Some members did relocate in Germany, mostly in and around Berlin.
