According to the "silver book" Mayflower Families Through Five Generations, 16:1:54: "The claim that Henry Alden of Billerica and Dedham, Mass., was a son of David Alden is unsubstantiated." More complete information can be found in The Mayflower Descendant, 43:21+, "Henry, The Non-Mayflower Alden," by Esther Littleford Wooworth-Barnes and Alicia Crane Williams. This is a very authoritative source and gives much evidence to disprove this theory.
