Middle English ago, agone, past participle of the obsolete verb ago 'pass', used to express passage of time.
When ago is followed by a clause, the clause is normally introduced by that rather than since: it was sixty years ago that I left this place (not it was sixty years ago since I left this place ). The use of since is redundant and is not correct in standard English.
