    McElhenny and Mccullough are both Scotch-Irish names. That is to say they came from Scotland originally and settled in Ulster during the plantations.

    Hi Follers, I believe Rob McElhenney may be 1/8th or 1/16 Scottish but I don’t know for certain. Rob’s paternal great-grandfather James Joseph McElhenney was born in Glasgow, Scotland but his mother was born in Ireland. James McElhenney’s mother was the only ancestor shown on btw.
