"I really believe they came from the Germanna colony with the Olar/Oyler family. but, then there were a lot of Fultz in New York."
There were also some in NC, Canada and in LA, although the latter were from French-speaking portions of Alsace rather than the German.
I haven't explored any possible Germanna Colony connection, but it's certainly a reasonable premise. The Huffmans (Henry, Jeremiah, & Elizabeth) who married Johannes and Catharina Voltz's children (Margaret, Christina, and David, respectively) were definitely from Germanna.
If I run across anything I'll let you know and I hope you'll keep me in the loop as well.
