From the Riedseltz records:

He is in the family list of 1804 in Riedseltz, same parents.
In An 9 (roughly 1800) is lived in house#136 Riedseltz. So, using the records below, we can construct a tree for you:

Etienne (Stephan) (??Balthasar) Berst, m. Catharine Friedmann, lived Riedseltz

2. Balthasar Berst, b. 1779 Riedseltz, d. 22Jan1848, m. Magdalena Lander, Marie Catharine Barbara Lantz
lots of kids
3. Magdalena Berst, d. 1776 Riedseltz, d. 1860, m. Heinrich Wagner, Riedseltz lots of kids
4. Martin Berst, b. 1787 Riedseltz (another Martin! This family just has to be related to J.G.'s group!)

This is probably a good assembly from the below data. I think Etienne's name was confused with Balthasar, either because Georg Jacob had a brother Balthasar, who the informant confused for Etienne (a french form of Stephan), OR because Etienne had two different first names. All of these records should be viewed, since places of birth for the wives or husbands at the marriages are often mentioned, and it would be a way to strengthen this. And of course the birth and baptismal records, not mentioned here, will help even more when we know who were the witnesses, and the missing children.

So, in sum, The Berst's of Soufflenheim ARE the Bersts of Riedseltz. Are they part of Johannes Georg Berst's family: can't say yet, but would be happy to bet on it. Thanks for pointing these records out, as they flesh out the Riedseltz Bersts a bit.
