WASHINGTON – House Speaker Nancy Pelosi’s eldest brother Thomas D’Alesandro III, the former mayor of Baltimore, died Sunday at age 90.

D’Alesandro, nicknamed “Young Tommy,” passed away due to stroke complications, according to the Baltimore Sun.

He was a one-term mayor from 1967 to 1971, leading Baltimore through a period of racial strife in the aftermath of Martin Luther King Jr.’s 1968 assassination, which led to riots in Baltimore and other American cities.

During his tenure he’s credited for appointing African-Americans to top positions within his administration.

D’Alesandro and Pelosi’s father Thomas D’Alesandro Jr. – called “Big Tommy” or “Tommy the elder” – had also been the mayor of Baltimore, bringing major league baseball back to the city.

“Big Tommy” also served Maryland as a member of Congress.

The 79-year-old Pelosi is the youngest – and the only girl – in the seven-sibling D’Alesandro clan.

And as the first female speaker of the House has outranked both her late father and her late brother in political prominence.

“My husband Paul and our entire family are devastated by the loss of our patriarch, my beloved brother, Thomas D’Alesandro III,” Pelosi’s office said in a statement. “All his life, Tommy worked on the side of the angels. Now, he is with them. With his commitment to his family and public service, his life has truly blessed America.”

Pelosi is currently out of the country, leading a Congressional delegation to Jordan, her office announced Saturday.

“With the deepening crisis in Syria after Turkey’s incursion, our delegation has engaged in vital discussions about the impact to regional stability, increased flow of refugees, and the dangerous opening that has been provided to ISIS, Iran and Russia,” Pelosi said in a statement.

Among those on the trip are House Intelligence Committee Chairman Adam Schiff (D-Calif.), who has become the face of the Democrats’ impeachment inquiry, and New York Rep. Eliot Engel, who chairs the House Foreign Affairs Committee.
