I don't think these three belong to George Sutton of Scituate, but they may belong to John Sutton of Rehoboth.
Red flags:
1) Esther and Margaret born in Hingham, England (no known connection to this family)
2) Ann born in Rehoboth, Massachusetts (ditto)
2) Esther born before her parents' marriage (March 13, 1635/36 in Scituate)
Esther, Ann, and Margaret might belong to the John Sutton family, apparently unrelated, who settled in Rehoboth: https://minerdescent.com/2010/06/07/john-sutton/
Consider detaching and merging here: John Sutton, of Hingham & Rehoboth
George and Sarah Tilden Sutton's children are listed and discussed here (note, two Sarahs, one of whom apparently died as an infant). (Don't know why Daniel is omitted--he is included in other genealogies.) http://olddobbers.net/sutton/sutton_george.pdf
Amy Nordahl Cote & Clifford Merriman
Correct - they had duplicates in the John Sutton family. Merged & done.
Thank you for spotting this.
