My greatgrandfather Fritz Soehlke emigrated in 1900 from his homevillage Reinsen near Stadthagen to Mecklenburg. He wanted to serve his time at the Dragoner's regiment in Ludwigslust.
When he still was a child he had admired those decorative blue uniforms at a manouvre. He had then decided to become a Dragoner later. Many many informations about this region you can find on the highly recomendable website of Karen Rowe,who has helped me a lot.
Also have a look at Alexandra Blume's website who is also specialised on Schaumburg-Lippe.
