Hi Robyn:
Perhaps I'm not much help. When I started this two years ago I was searching for either Poffenbach or Paffenbach.
A recent connection to a distant cousin has confirmed by marriage certificate that my GG-Grandmother was Catherine Pfaffenbach.
She was married to Julius Heuple. They were reportedly both born in Germany and came to the U.S. via Pennsylvania. They later ended up in Toledo, Ohio.
Catherine's husband Julius was a veteran of the American Civil War having served in the Union Army. He died at an early age, perhaps of wounds in Milwaukee.
Catherine died in 1921 in Toledo, Ohio.
That's about all I have.
Best of Luck
