Puzzle - Schlegel roots

NO CHANGE SINCE 1Q

Wilhelm August? Schlegel is the oldest of my Schlegel line appearing in the Lutheran church records for Kolmar.  His occupation was weaver, according to the church record for the wedding of his son Georg.  In reading about the history of Kolmar, I learned that a group of weavers from Germany settled in Kolmar about (...date...), but as yet, I've been unable to discover where this group came from in Germany, which might lead me to where my Schlegel line was living before Prussia.

August Friedrich Vogelsang is the oldest of my Vogelsang line appearing in the Lutheran church records for Kolmar.  His occupation was butcher, according to the church record for the wedding of his daughter Emma to Georg Schlegel; Georg's occupation is also listed as butcher. Georg's son Paul Wilhelm, my grandfather, was a butcher after immigrating to NYC, as were the 3 of my grandfather's 

Vogelsang male cousins who also immigrated to NYC.  As yet, have no idea where my Vogelsang line originated in Germany, before settling in Prussia.
