The Duggars, the Arkansas family whose lives are chronicled on the TLC program 19 Kids and Counting, have had their second grandchild.

Josh Duggar, 23, and his wife Anna, delivered an 8 lb 5 oz baby boy at home on June 15, People magazine reported.  The baby, whose name has not been released, joins 20-month-old sister MacKynzie.  A source close to the couple confirmed to People that the baby's name will start with "M," following in Jim Bob and Michelle Duggar's footsteps (all of their 19 children have names that begin with "J").
