Josue and his first wife had a different son named Heinrich Burkhard. The reuse of the name suggests that the first Heinrich Burkhard died young (it was not uncommon at the time to give one child the name of a sibling who had died).
Nothing is known about his life including where he lived, what he did, whether he married or had children.
