Gloria Steinem is reported as my 8th cousin, twice removed, through our MRCA, Johannes Steinbach (1618-1681).   Yet, each of our next generation is defined as Johann Jacob Steinbach (1640-1727) and Johannes Steinbach (1640-1727).  Now unless these two were twin brothers and happened to also die the same year, I would venture the guess they were the same person and Cousin Gloria and I might be closer related.   Someone did not even do a reasonable check within the app.
