Neither Hartford's archdiocese nor Rockford's diocese has ever suffered within its borders the existence of an SSPX chapel to the best of my knowledge. There did exist within the geographical boundaries of the Hartford archdiocese an "independent" chapel at New Haven (St. Clare's Priory) which had extremely occasional Masses (three or four times a year) said by Fr. Paul Wickens (recently deceased) of Newark, New Jersey. To say the least, that was not the reason for the late Archbishop John F. Whealon's early enthusiasm for the establishment of Tridentine Masses at New Haven (Sacred Heart Church) and Hartford (Our Lady of Sorrows Church).
The SSPX has never existed in Greenville, SC or Columbia, SC or Charleston, SC, and thanks to the indulgence of His Excellency, Robert J. Baker, bishop of Charleston, we will soon have Latin Mass locations in all three of these areas. This in a diocese that is less than 3 percent Catholic. Had NOTHING WHATSOEVER to do with SSPX.
