This New York Times article says that Judge Curiel’s father Salvador arrived in the United States in the 1920s, eventually becoming a citizen and working as a steelworker. Trump’s mother, Mary Anne MacLeod, arrived in the United States from Scotland in 1930. Mary Anne became a US citizen in 1942.
Since Trump and his parents have been major public figure for decades, we have more details about them than the Curiels. But even a brief bit of research says that Judge Curiel’s father’s immigration to the United States predates that of Trump’s mother.
