Carl,
The same situation is seen in my husband's family from Gorodek near Bialystok.
He used his wife's surname for several years after arrival, and then changed the surname. His brother used their father's surname. They both arrived in The U.S. in the mid-1880's.
In my family from Ustrzyki Dolne there is one person who used his mother's maiden surname, and that branch retains that name to this day. His siblings all used their father's surname.
So, why one sibling using the mother's maiden name, and the other siblings using the father's? They all arrived in The U.S. within a few years of each other circa 1910's.
Does anyone have an explanation why this occurred with some immigrants?
Regards,
Sherri Bobish
