Christopher,
I have no information about any Ziemer line in Pa., sorry. All I find on my
line is that they entered at NY and worked "briefly" on the east coast
before arriving in Martin co., MN sometime before 1871 [that was when their
first child, my great-grandma, Olive Ann Ziemer was born.] Wish there was
more that would be helpful for you.
