I was doing some sourcing when I ran across two apparent twins: Stanton Williams and William Williams both with 5 May 1782 birth dates; parents John and Content. The only place I find them as twins is in Wheeler's History of the Town of Stonington, page 672. Stanton does not appear in the Barbour Collecion for Stonington at all.
Barbour has the birth of William Stanton (Williams) - one person - on 4 May 1782, the son of John and Content.
Ancestry.com has entries in its Connecticut Church Record Abstracts for Stonington:
"William, s.[son] Capt. John & Content, bp.[baptized] Dec. 23 1784." Vol. W, p. 251.
"William-Stanton, Desire & George, children of Capt. John & Content, bp. Dec. 13 1785 at home, 'she being able to come to church.' " Vol. 4, p. 76.
Note that the 2 entries come from different sources. I surmise that they are different entries for the same event, and the one year difference is an error in one or the other.
The lack of any separate entry for a Stanton Williams, son of John and Content, and the hyphenated name, indicating a single person, I believe leads to the conclusion that Stanton Williams is a non-existent person, and "his" profile should be merged away into William's profile.
