Avraham Yitzchak Halsztuk (Halsztok) - Marriage

Possibly. On the other hand, there's another Abram-Icek Halsztuk, son of Chaim, born in Ostrowiec in 1894. Also, the Bajla Rejla who died 08-Mar-1933 was the DAUGHTER of Abram Icek, according to JewishGen, unless that's a mistake. She was also 48 at death i.e. born circa 1885, unlikely to have been Avraham Yitzchak's first wife.

The one born in Ostrowiec in 1894, son of Chaim may possibly have been a son of Chaim Shmayahu Halsztok.
