Advice before editing this pre-1700 UNKNOWN profile?

Question

I have information to contribute to the profile of Sarah (UNKNOWN) Peck. This is what I can add:

• Last name at birth is Peck. Married name is Holt. 

These are the sources I am using:

• Jacobus, Donald Lines (compiler). Families of Ancient New Haven, Vol I-VIII. and Index Vol IX New Haven: 1931. Reprint, Baltimore: Genealogical Publishing Co., Inc., 1974, 1981, 1997. Originally published as New Haven Genealogical Magazine, Volumes I-VIII. Rome, NY and New Haven, CT 1922-1932.

I am not allowed to edit this profile. 

Answer 1

The profile cites the excellent source you are using (along with others), and the profile states that little is known about her (this includes her LNAB).

Where did you see an indication that her LNAB was Peck?

Answer 2

When she married William Holt, her last name at birth was unknown. Her second marriage was to William Peck, per the source you are citing.
