Hello Paul, No, these Hoeppner(s) are Mennonite. The mennonites came out of the mid 1500's anabaptist movement happening in Prussia, Netherlands, and Switzerland area.
One of the early founders was Menno Simons. The first faction was Swiss and Dutch. The movement then moved to Prussia and picked up a German faction. They lived in West Prussia, modern day Ukraine and moved again in 1789 and up to Russia, part of what is now modern Poland. One early faction went to Pennsylvania. 2nd wave went to PA and up into Canada and more specifically the Red River Valley in Manitoba
Some Hoeppner's were also part of the Luthern faction and I have seen some sites referencing a Jewish faction - but I can't remember where. If you're trying to locate that information, I can keep my eyes out for you. Marlene
