Ken,

If your looking for someone from Baden, don't you thing that a message board or mail list that serves that area might be the place to post a query?

However, just as in Alsace or Lorraine they will ask if you have done your homework and researched all the information where Jacob lived, because the exact village name is usually required. Exact information is also good to know: birth date, marriage date, any siblings known, family religion, and etc.
