Stein born 1878 married Gomringer
I am searching for information on Martin Henry (Henrich) Stein born in 1878 in Switzerland, area unknown. He was married to Amelie Gomringer, vital data unknown. They were found in Lehigh County, PA 1920 Census. They had three known children Martin Henry born 1913; Amelia born 1907 and Ruth both 1915. Any assistance would be greatly appreciated. If someone knows what I need to do to contact genealogy research in Switzerland, please let me know.
Thank you
Sharon
