Albert Barnes Commentary 2 Timothy 4:19

"Salute Prisca and Aquila, and the house of Onesiphorus." — 2 Timothy 4:19 (ASV)

Salute Priscilla and Aquila. Prisca, or Priscilla, was the wife of Aquila, though her name is sometimes mentioned first. Regarding their history, See Barnes on Romans 16:3.

They were at Rome when Paul wrote his epistle to the Romans, but afterwards went into Asia Minor, which was the native place of Aquila, Acts 18:2, and where they probably died.

And the household of Onesiphorus. See Barnes on 2 Timothy 1:16.
