Hi, I descend from the Rosenbusch family of Borken(Hessen). Joseph Rosenbusch is the earliest known with that surname. He was born about 1743, His father was Elchanen born about 1710. There are about 1500 members of the tree.
Also, three brothers of my Wirth family married 3 Rosenbusch sisters from Gaukonigsberg. I have not researched this family, but am in touch with descendants.
