Third child of Josh and Anna Duggar, adding to the already very large Duggar family of 19 Kids and Counting fame.
He was given the full birth name of Marcus Anthony Duggar.
While his grandparents Michelle and Jim Bob Duggar elected to name all of their children with a name beginning with the letter "J," he continues his family's tradition of names beginning with "M."
His siblings are Mackynzie, Meredith and Michael. He has 18 aunts and uncles.
One of his aunts is Josie Duggar who is only about 3 years older than him.
