I'm looking for my great grandparents; John Simon b.7/30/1873 and Barbara Dorner b. 1881 in Glagowatz Romania. They married on 1/25/1900. Barbara's father was Josef Derner b. about 1856 and lived at 268 L Ansgasse in 1921. Any information on them or how to find information would be very helpful. Thank you, Linda
