From Face[t]s of First Language Loss, by Sandra G. Kouritzin (Routledge, 1999), pp. 160-161:
Alex is a borderlander who is also the son of borderlanders. His mother was born to Russian immigrants in Chicago, but moved to Russia when her parents returned there after the Revolution. She moved into a border town that had once been the southwest part of Poland, just north of the Ukraine, but which had become part of White Russia. Living in such a linguistically diverse region, Alex’s parents spoke Polish and White Russian (a dialect) and standard Russian, depending on the situation. When Alex was born, they adopted Polish as the home language. They moved to a vibrant Polish-speaking community in the United States when Alex was 3 years and 3 months old. They later moved to northern Canada where several of their relatives lived, and where they were able to communicate in Ukrainian, another language spoken by both of his parents.
Alex remembers beginning school, and he remembers the day when his Polish first name was changed to Alex so that his teachers could more easily pronounce it. Like Kuong, he has no recollection of Grade 1 and 2, though he has clear memories of Grade 3 and following (after he could speak English) and of playschool and kindergarten (when he played and had fun in Polish). While Alex was growing up, his parents relied on him to translate English into Polish for them; his father worked in a foundry and did not require English, while his mother stayed home. When I met him, Alex could speak only a little, broken, Polish, and could follow a very basic conversation in Polish. He remembers being much more fluent, and he feels like he is losing Polish bit-by-bit, day-by-day.
