Could clarify more about "Colonial Era"? Which country and time period?

I think it's just you, most were French and Spanish going by your broad definition.

As others have said, your phrasing here is so broad as to be impossible to answer. The Anglican Church's Society for the Propagation of the Gospel was a missionary organization, and yet it did not employ an usually large number of Germans. The Jesuits were Christians, yet drew their numbers from all over Europe. And, since this is Reddit, you're probably American and probably mean "colonial period" as "the east coast of North America before the American Revolution." With that framework in mind, I can say that a large number of people establishing new religions during this period were Germans. There are a number of reasons for this. Germans had a long tradition of religious experimentation, going back well before Martin Luther. The chaos of the Thirty Years War also did little to endear the major established religion to many German people. German was also politically and geographically fragmented, providing a lot of space for people to experiment with religion without a strong organized crackdown.

I was reading about Australia and New Zealand in the 1800s and German Missionaries seemed to pop up more than British or otherwise.

And then I thought about it, and I seem to remember that Africa had loads of German missionaries as well.
