Hello, I am not sure if this post is still active, but I wanted to attach the information I have.
Hermann had a daughter, Lidia Helene Johanna Ihne. She was born in 1850. She married Hermann Henry Heger on March 21, 1874. They had a daughter, Stella Heger (1875-1932). By 1885, Lydia had married again to William Casper.
Let me know if anyone is still active on this thread.
Thanks,
Rolf
