William J. "Billie" Guillemin, Jr., a lifelong resident of Clifton Heights, passed away on January 30, 2026. He was 72 years old. Born in Ridley Park, Billie was the son of the late Jane Ora (Hendricks) and William J. Guillemin, Sr.

Billie worked as a postal worker for USPS for more than 30 years until his retirement in 2008. He loved music, animals, collectibles, and sports, especially the Philadelphia Flyers and Phillies. He was a personable, happy-go-lucky person who lit up a room and would strike up a conversation with whomever crossed his path. He will be remembered for his mild-mannered, easy-going spirit and willingness to drop everything to help someone else.

He will be deeply missed by his three daughters, Daphne Guillemin of Paoli, Yvonne Guillemin of Berwyn, and Noelle Guillemin of Newtown Square; four grandchildren, Lexi, Madi, Christian, and Zach; sister, Linda Weindel of Glenolden; and many nieces and nephews. In addition to his parents, he was predeceased by his beloved dog, Bailey.
