Matthias was born about 1600. One source says he was born in the Black Forest. He passed away before 1659.
The Riedesel source listed has a vast database for ancestors from the Schleswig-Holstein area. That being said there are no sources listed so it's not possible to know which entries are actually fact vs those which are educated guesses. Given the author has been to this area multiple times my sense is much of what is contained is based on sound research. Riedesel.org (source is unverified)
