Question: Where was the Melchizedek Priesthood restored?

The bestowal of the Melchizedek priesthood occurred in Harmony, but the ordination to offices was deferred until later

Secured the copyright on June 11
Oliver's letter to Hyrum on June 14
Joseph's details of how busy they were during this time period at the farm ^[2]

They were told to “defer this our ordination until such times as it should be practicable to have our brethren, who had been and who should be baptized, assembled together, when we must have their sanction to our proceeding to ordain each other.” ^[3]

There are many times^[4] when Oliver confirmed without error that the sequence of events occurred as shown above.^[5]
