Looking for any more information on current Ratmeyer's or other version's of family history.

I have a copy of a genealogy printed in 1931 in German with an English translation for anyone interested, which traces that line back to the early 1700's. Towns in Germany include Lüdge, Sabbenhausen, Lüdenberge, Radsieke, Ratsiek, Elbringen, Hörter, Wörderfeld, Detmold, Neerfen, Falkenhagen

Johannes Arndt Ratmeyer 1760 - 1832 was the most wealthy descendant in the area who's fortune was squandered away by his sons.

Currently, a Friedhelm and Kornelia Ratmeyer operate a pub called Braugasse in Detmold. If anyone has any contact information for them, I'd appreciate it. Friedhelm is getting up there in age and has been a source of information on the German side to some relatives.
