I believe these are my great-great grandparents. They had 11 children so I am hopeful there are other surviving descendants like me. They were born in Germany and immigrated to the U.S. and lived in New Jersey (Newark and Irvington). Would love to hear from others who can trace their tree back to Ferdinand (born about 1848) and Bertha (born about 1852). I believe I am a descendant of their son George.
