Armin is buried in Zakamenne, Slovokia as per the municipal records of the town of Zakamenne. He is also named in the town history book as someone who played a role in the development of the municipality during the 1800s.
Looking at Herman's timeline, I see that he must have married Anna when he was older than usual and she was young, to fit in all the births at the right times. Maybe Anna was a second wife. I guessed at her birth and death dates to fit in the long span of childbearing. I gave her what I thought might be an average lifespan. Maybe we will be lucky enough to correct her dates someday. @Herman Heda
I notice that there is a big gap between Morris' and Pinkus' births. Morris was born about 1865, and Pinkus about 1876. It's possible that Morris was born to a previous wife of Herman's. Unfortunately his death certificate has "Unknown" for the parents' names.
