Are you still searching? My great-grandmother was Clara Loughlin, born 1872 in New York and was raised in San Francisco from 1873. Her father Peter J Loughlin came from Prince Edwards Island, CANADA as well as his wife Mary Burke. To be honest not sure if they spelled their name as Loughlin or Laughlin as I have found both spellings, but Loughlin is the majority. I have found no futher information regarding Peter or Mary Loughlin beyond census records, voter records, & phone listings in SF and SF Bay Area.
