You're welcome,

kupan@netzero.net In the meanwhile I looked up the Jewish hospitals in Budapest in the 1920s:
http://www.cylex-tudakozo.hu/ceg-info/mazsihisz-szeretetk%C3...There were four, the Amerikai ut in Dist.XIV, the Szabolcs utca in Dist.XIII, and the Maros utca and Varosmajor utca both in Dist.XII on the Buda side of Budapest. The first two on the Pest side are the most likely places if your g.g.mother passed away in hospital. The Szabolcs utca is the closest to Dist.VII, the Amerikai ut also not far, this last one still functioning Jewish hospital, the only one in Central-Europe. I still have to check the District numbers, it may have been different in 1926.
