I am researching great, great, great, grandparents, born in Austria, 1860's, died in London. Lewis was called Eliyohu Tzvi. Debora father was called Chuni Tzvi Schwartz. 
Lewis and Deborah had a son, Philip, who shortened his surname to Schiff.
Anyone who has further info about the Schiffenbauers, I would be very grateful if you could please contact me on my email address below.

Many thanks,
