HI, I too am researching the loughman family. My great grandfather was Timothy Loughman, He had several children by one Ann Maloney.
One of the boys names were John Loughman,he was according to my records born on 3-25-1879 in Scranton, PA. My great grandfather was botn on 12-25-1853 in Ireland, maybe he had other children before he married Ann Maloney. Maybe this might help, not sure. Write me if you can hel me too in locating info on the family
