Native Languages

One line through four generations:

My dad's mom's native language was Polish.
My dad's native language is German.
My native language is English.
My son's native language is Japanese.

All four of us were born in the United States of America.

父方の祖母の母語はポーランド語でした。父の母語はドイツ語です。僕の母語は英語。息子の母語は日本語。全て4人は米国の生まれ。

My four grandparents all had different native languages: one each with Polish, German, French, and English.

Three were born in the USA; only the native English speaker, my maternal grandmother, was not (she was born in Canada).

僕の祖父母、4人はそれぞれ違う母語があって：ポーランド語、ドイツ語、フランス語、英語。一人以外は米国の生まれ。母語が英語の母方の祖母だけは別の国の生まれ。
