A US couple who have 14 children with names all beginning with J, are expecting a 15th child.

Michelle Dugger and husband Jim Bob say the new arrival will also have a first name beginning with J - Jackson.

They said they never intended to bring up such a large family, says Sky News Online.

Michelle told CBS: "I don't think it was our intention when we first married but I think we realised children are a gift."

So far the couple have Jana, John, Jill, Jessa, Jinger, Joseph, Josiah, Joanna, Jedadiah, Jeremia, Jason, James and Justin.

The deeply-religious southern Baptist family is schooled at home and sew their own clothes to cut down costs.
