According to the documentation that I have, both were from Merkel. They immigrated to the United States at different times. Katherine Trupp and her family appr. 1901, to the Southwestern Nebraska area, and Jacob Petrie immigrated in 1902. It is not clear where or how they met. But they were married in Fort Collins Colorado in 1904 and farmed/lived in the Wellington Colorado area. Jacob died in 1944 and Katherine in 1965.
Any help you could provided would be appreciated.Thanks.
