Isaac Allerton, was born in Plymouth Colony, Massachusetts, to Isaac Allerton and Fear Brewster some time after the 22 May 1627 division of cattle and before 21 Sep 1631.[1][2]

He graduated Harvard College in 1650.[1]

He married first Elizabeth (Unknown) about 1652 and they had two children:[1]

  1. Elizabeth, b. 27 Sep 1653;
  2. Isaac, b. 11 Jun 1655, d. bef. 25 Oct 1702.

After the death of his first wife, he married the widow Elizabeth (Willoughby) Overzee Colclough,[3] daughter of Capt. Thomas and Alice (___) Willoughby, in Virginia, after 8 Sep 1662 and before 20 Feb 1663/4.[1] They had three children,[4] born in Westmoreland, Virginia, as follows:[1]

  1. Willoughby, b. ca. 1664;
  2. Frances, b. ca. 1669;
  3. Sarah, b. ca. 1670.

He possibly had a 4th daughter, Mary, who married John Newton, Jr.[1]

He was a Justice of Northumberland County in 1663. He was also a Colonel in the Virginia militia.[5]

He passed away sometime between 25 Oct 1702 and 30 Dec 1702 (date of will and probate), in Westmoreland, Virginia,[1] perhaps in Cople Parish. In his will, he names his daughter Sarah Lee and grandson Allerton Newton, daughter Elizabeth Starr alias Heirs (Eyre/Ayre); daughter Traverse (dec'd) and her daughters Elizabeth, Rebecca and Winifred Travers; and son, Willoughby Allerton.[1]

On 4 May 1680, "[w]hereas there was agreements between Mr. Isaac Allerton sometime of New Haven in the Colony of Connecticut now deceased and Will[iam] Holt of the aforesaid New Haven respecting a small quantity of land granted to the lots that butted on the Oystershell Field which proportion ofland the said Will[iam] Holt did make and pass over to the said Allerton ... and there having not yet been any written or recorded deed to declare the same now I Johanah the widow and relict of the said Allerton ... and well knowing the agreement with the said Holt and John Holt son of the said William . . . do both of them ratify and confirm the said agreement" [NHLR 1:38]. On 19 May 1684, "Elizabeth Eyer, formerly Elizabeth Allerton now wife of Simon Eyre of New Haven ... , having the reversion of a house that my grandmother Mrs. Johanna Allerton now dwells in situate in New Haven aforesaid with the appurtenances thereunto belonging . . . when it was in the possession of my deceased grandfather ... together with the house was bought by my father of my grandfather's creditors and given to me by my father Mr. Isaac Allerton to be possessed thereof as my propriety and right given me by my father after the death of my grandmother Mrs. Johanna Allerton which reversion ... I the said Elizabeth Eyre for good consideration me thereunto moving do give, grant and alienate ... unto my dear and loving husband Simon Eyre" [NHLR 1 :265].[6]

Allerton-102 and Allerton-5 do not represent the same person because: looking at, this people are not the same.

Elizabeth (Unknown) Allerton is the only mother of Isaac Jr's son Isaac. Elizabeth Willoughby has no son Isaac.
posted by Traci Thiessen
Both wives Elizabeth are currently shown here on WikiTree as having sons called Isaac.

Is that an error?

Allerton-186 and Allerton-5 appear to represent the same person because: Same name, wife, parents, death, birth is off by 3 years (Allerton-5 has sources) but this should not hold up a merge.

According to the General Society of Mayflower Descendants, this couple were the parents of at least four children: Elizabeth, Frances, Sarah and Willoughby.
