Jonathan Gosselin is the middle child of three boys. His brothers are Thomas and Mark. His father, Thomas Gosselin, was a pediatric dentist who died in 2005. The couple met on October 5, 1997 at a picnic. According to the "How It All Began" episode, Jon was working at a hotel and Kate had recently graduated from her nursing program. According to Kate, "I never believed in 'love at first sight', but this came really close." They were married on June 12, 1999 in "a perfect garden wedding with equally perfect weather".
Kate Gosselin is one of five children. She has three sisters and a brother. The latter, Kevin, is often seen on the television series with his wife, Jodi, and their four children Ashtyn, Braden, Alyssa, and Benney.
Kate's desire to start a family was met with a feeling that she would not be able to conceive. She underwent testing and was diagnosed with polycystic ovarian syndrome. The couple decided to turn to fertility treatments and immediately began intrauterine insemination or IUI, a procedure where no embryos are left over from the procedure. By February, Kate was pregnant with twins. The couple was thrilled, admitting to having prayed for twins because they were both baby crazy and feared they would fight over one baby. On October 8, 2000, Cara and Mady were born, after a "rough" pregnancy. They were born six minutes apart. In birth order, they are Cara Nicole Gosselin and Madelyn "Mady" Kate Gosselin.
Jon and Kate are parents to 8 children:
- Mady Gosselin
