iced-I checked wikipedia and two other websites and ,indeed, the Ari’s father was an ashkenazi (luria was the family name- one website even asserts that his ancestors came from brisk- russia)although his mother was sefardit.
He grew up in egypt when his father died as he was very young- and hence, the common assumption (at least by me) that he was a sefardi. Still, I’d like to know what minhagim he followed, the Rosh (ashkenazi) or the Rambam (sefardi)
