I think more important than what ship he arrived on is sorting out the contradictions on his profile. I found the marriage record that supports Christian's maiden name being Turner and added the source to Robert's profile but as I looked closer at the profile I saw some contradictions so someone needs to look closer at things. It says, "Robert Carver of Plymouth Colony "almost certainly" the Robert Carver who with his wife Christian had three children baptized at St. Mary Matfelon, Whitechapel: a daughter Elizabeth in 1632, a son William in 1635, and a son John, on 23 Dec 1636." but then it says, "Robert and Christian had only one child:
John Carver, b c. 1637 England; m 4 Nov 1658 to" and doesn't complete the sentence. There can't be 3 and also only one child at the same time. There is a christening source with these parents names stating 23 Dec 1636, Saint Mary Matfelon, Stepney, Middlesex, England. But if I have the locations right, the christening was over 80 miles east of the marriage. Then his profile says born in Duxbury, Plymouth, not England. There is one contradiction after another. I think someone needs to start from scratch, using only sources then add the rest in a research notes section.
