The parentage attached to Unknown Phelps should be addressed by the PGM and Quakers projects.
The parents are currently marked Uncertain. The given name of Mr Phelps in the Massachusetts Bay colony is nowhere recorded. The nickname "Henry" has remained on the profile as it is frequently encountered as an erroneous and/or unproven given name. If the given name of Mr Phelps is unknown it would follow that his parents would be Unknown rather than Uncertain (yes, there could be exceptions to that but those are not in play here).
The question is of interest to the Quakers project as Mr Phelps is the father of one of the founders of the first Quaker meeting in Salem (and likely first in Massachusetts), Nicholas Phelps. (Note: I see Nicholas has developed an unmanaged duplicate profile which I will adopt and merge in the project managed profile.)
Thanks, Anne. Unknown Phelps is a 10th ggf and I have never found any documentation of his given name or place of origin. I'll wait to see if Michael Cayley or other colleagues in Quakers project have anything to add. Anderson shows the sons Nicholas and Henry arriving on the Hercules 1634...wonder if the father arrived later. There is considerable disagreement about the passenger list for the 1634 sailing from Sandwich of the Hercules.
