Oh, this is too funny!!
This is what I got when I 'googled' Who is the grandfather of John the Baptist?
Barachiah (or Barachias), who was the father of Zechariah (or Zecharias), who was John the Baptist's father. Zechariah (Zecharias) wrote the Book of Zechariah in the Old Testament (Zechariah 1:1) and was martyred as stated by Jesus (Matthew 23:35). John the Baptist's great grandfather was the prophet Iddo.
Sorry, this is the wrong Zachariah. They lived 500 years apart. What was the source of this garbage answer? I can't find it.
