I have done an extensive amount of research on the Guldenschuh surname in the United States. So far, I have been able to tie most of the Guldenschuh's who originally resided in the New York, Pennsylvania and Ohio areas together. They include Theresa, her four sons, J.P., Charles, Julius Francis, and Isaac. Isaac's children include: Wm, Jacob, Charles F, George, Edward, Charles H., John, Lottie, Laura, Addie, Mary, May, and Isaac Jr. I have the following Guldenschuh's that I have not directly tied to this family who resided in the United States. If you are related in any way, I would love to hear from you and exchange information.
Frederick Guldenschuh, m. Magdalina. Arrived in US in 1854. This family is found in Indiana. (Name spelled Guldenschue)
Jules Guldenschuh m. Dora Breiding. Arrived in the US in 1877. This family is found in Massachusetts.
Charles Guldenschuh m. Elizabeth arrived in US in 1890. This family is found in Kentucky. (Birthdates on this Charles do not agree with any of my records.)
Peter Guldenschuh m. Kate found in New York. (I believe him to be JP, son of Theresa but have no proof)
