Paddy McGuinness has uncovered a surprising ancestral link to U.S. President Joe Biden during his appearance on the BBC show Who Do You Think You Are?, scheduled to air on August 22. McGuinness discovered that his great-grandmother, Bridget McGuinness, was baptized in County Mayo, and his great-great-grandparents lived near Biden's ancestor, Edward Blewitt, in Ballina. The presenter expressed a strong spiritual connection to Ireland, feeling moved by his heritage despite previously feeling 'ignorant' about it. He highlighted the emotional significance of seeing his grandfather's war medal as a poignant connection to his family's history. Biden has historical ties to County Mayo himself, having visited the area and received a brick from his ancestral home. Both men share a connection to the same region, adding a layer of historical intrigue to McGuinness's journey.
