Jill Biden visits Burlington, once lived in Mahwah NJ
Biden was born Jill Tracy Jacobs in June 1951 in neighboring Atlantic County's Hammonton, also the birthplace of her father, Donald Carl Jacobs. She was the oldest of five sisters, followed by Bonny, Jan, Kim and Kelly. When Biden was a child, the family moved to Hatboro, Pennsylvania, about halfway between Philadelphia and Trenton. Both Donald and wife Bonny are now buried in its cemetery, their funeral notices said. Biden's early days in South Jersey are well-known. But less noted are her childhood roots in Mahwah, in Bergen County. You won't find it mentioned in her Wikipedia biography...
