Kudos, Dave, that is correct. I'd love to meet you there...I haven't yet gone there because it's far away, not a day trip.
While birth, death and marriage records have consistently been filed west of the river Rhine since the late 18th century due to French occupation this didn't happen in the rest of Germany until such became a law in 1875.
There may be a baptism record in the church registers (greatly digitalised and online), but access is pricey.
(As for the naming - St. Georg was built in 1119, don't know when it was named after Georg, Saint or not...)
