Vogeltje Deutz was a daughter of Jacob Levie Deutz and Sara Waas. She was unmarried.
Certain is that she had three sisters from her father's first marriage: Roosje, Grietje and Mina and another sister from her father's second marriage: Betje. Only Roosje, married to Philip Mok in 1892, has passed away before the war. The others have been killed all in the Shoah.
