Ellen, I should have been clearer. I did not find Hannah Dean/Deans when I searched the name Hannah Daines. After I found her by Dean in ancestry, I searched americanancestors again using Dean as the surname, and found the two records you show.
In this case, I was trying to find a source that matched the data in the existing unsourced profile, which I believe I did, sufficiently to say they matched the profile. I did not consider that perhaps the entire profile was incorrect. There are several more unsourced Dains from the same time period (likely brothers and sisters), and as I look for sources for those, I think we'll find further verification of Hannah's data.
Interestingly, the Hannah Daines search in americanancestors with only "Connecticut" as a search parameter, although most results were Downes or Dunk, I did find the following in the Barbour Collection Norwich vital records (Norwich being the ascribed location in the orginal profile) :
Abell Deens & Mercy Polley were married to Each other January 28th, 1734/5 by me Henry Willes Paft[r] of ye fecond C[hh] in norwich. Entred January 14th 1735/6. (Barbour, Norwich-V1, p. 165)
Hannah Deens Daughter of Abell & Mercy was born Janu[ry] 5th 1735.
Lucie Deens ye Daughter of Abell Deens and his wife marcy was born ye 7th of July 1738.
Jemima ye daughter of Abel Deens and of his wife Marcy was born may 21st 1740. (Ibid., page 166.)
As you said, this record is roughly the same time frame and the actual location in the profile, so it could cause potential confusion. However, Hannah's two sisters, Lucie and Jemima, do not appear as siblings in Hannah Daines' profile, so I think it is acceptable to cross Hannah Deens of Norwich off our list.
