The only evidence of George is that of his Blessing on 30 Oct 1756. Johann Jacob, one of his brothers is well documented as having been born on 15 Apr 1756 and having been baptized on 30 Jul 1756. Since George was not baptized at the same time as Jacob, It is unlikely that they were twins. More likely, George was conceived after Jacob and was born prematurely and either died shortly after birth or may have been stillborn. It would have been normal for him to have been blessed by baptism after his death.
