I have checked the St. George Vital Records, Cemetery Inscriptions, Rockland Vital Records and also the Lime Rock Gazette and Rockland Gazette death notices prior to 1892. I have not even found the name of MacLellan or Noonan. I did find McLellan in St. George but none of the names that you provided. Sorry I couldn't have been of more help. There were many granite quarries in that area and they he might have been a worker there. There were also quarries out on Vinalhaven and more of the other islands.
