Duggar family welcomes first grandson - two and counting for grandkids

josh-and-anna-pregnancy-picture.jpgThe Duggar family, made famous on TLC's "19 Kids and Counting," has expanded by one. Josh Duggar, the eldest son of the 19-child strong brood of Jim Bob and Michelle Duggar, has welcomed a baby boy with his wife Anna on Wednesday (June 15), reports People. The baby boy is the first grandson for the Duggars.

Josh and Anna already have a baby girl, MacKynzie, who is 20 months old. They have not revealed their son's name yet, but they do say they're sticking with the "M" naming theme. The elder Duggars named all their children with "J" names (Josh, Jana, John-David, Jill, Jessa, Jinger, Joseph, Josiah, Joy-Anna, Jedidiah, Jeremiah, Jason, James, Justin, Jackson, Johannah, Jennifer, Jordyn-Grace and Josie).

MacKynzie and as-of-yet unrevealed baby boy M will have a playmate their age - their youngest aunt, Josie, is only 17 months old. Congratulations to the whole Duggar clan. You can follow their story on "19 Kids and Counting," which airs Tuesday nights at 8 p.m. ET on TLC. A Josh and Anna special airs Friday, June 17 at 8 p.m. ET.
