I couldn't tell if they were part of Canterbury or not. Can you?
The answer is no. Traditional Anglicans split with the Church of England in the 1970's when that group endorsed abortion, women's ordination, etc., etc. Many former Anglicans/Episcopalians have joined the Catholic Church but many others want to keep some Anglican rites. I think it would be fine for the Catholic Church to have an Anglican rite.
The ANGLICAN CHURCH IN AMERICA (ACA) is among the largest of several "Continuing Churches" which emerged from the AFFIRMATION OF ST. LOUIS and the 1977 gathering of faithful Anglicans which produced that document. ...
THE ACA IS NOT PART OF THE EPISCOPAL CHURCH USA OR THE CANTERBURY-BASED ANGLICAN COMMUNION
They aren't.
