Paulina Marcovici (Pauline Markowitz),family and children

Pauline Markowitz changed her name from Paulina Marcovici after (or during) immigration. Her children are: My grandmother, Helen (also called "Lana" short for Hebrew name Ilana?), and my great-uncles Herman ("Hymie"), and Harry who were all born in Romania. After immigration, Henrietta, Oscar and Jerome were born in the US (not pictured here).

The photos below of two men (may be the same person) are unidentified.
