Ken, looks like two Abigails have been merged, one born c1685 the other dau of Elizabeth.
Abigail Blakeman (born c 1685) married 1681 to Ebanezer (b 1682), first child born 1679.
Ebenezer Blakeman is also showing as married to Abigail Blakeman in 1692 (when he was 10 years old?)
It looks like a lot of creative research has been put into this group and some serious actual research is required.
It looks like John Wilcoxson and Elizabeth (Bourne) Wilcoxson did not even have a daughter named Abigail. https://www.wikitree.com/wiki/Wilcoxson-22
Abigail Blakeman it seems is actually named Patience Blackman formerly Wilcoxson
Born 21 Feb 1664 in Stratford, Fairfield, Connecticut Died about 1691 at about age 26 in Connecticut
I'll leave this a few hours/days to see if anyone else wants to comment before i start editing
