Focusing on the left side of the table/starting closest to the camera...
1. Ona Petrauskiene, a more distant cousin.
Start by thinking of (our grandmother/greatgrandmother) Mary's father, Jeronimas.
Ona would be the granddaughter of Jeronimas' brother.
2. Antanina... the youngest daughter of Mary's brother Frank Kazlauskas.
3. Antanina's husband Juozas.
4. Aldona - another of the daughter's of Frank Kazlauskas.
5. Janina's husband, Juozas. (Janina being the daughter of Mary's brother Joseph).
6. Janina herself - barely visible here... she's wearing a dark dress with a white collar.
