The research I have done indicates she was born in England, and migrated to America with her father, mother (Sarah?) two sisters; Hannah and second sister's first name unknown, and brother John.
An excerpt from "The Hannums of Massachusetts" by William Hamilton Hannum states George arrived in Wethersfield, Ma about 1636.He moved to Springfield, MA in 1646.Sometime between the time he arrived in America and his move to Springfield his first wife died. He married Hannah (Lambe) Haynes, widow of Edmund Haynes,on 29 June 1648. They had one child; Esther (Hester), born 22 June 1649. He, then moved the family to Northampton, MA, where he died 29 Dec 1676.
John was b. abt 1619/24, m. (2d) Mary (Gridley) Seymour 20 Dec 1655 in Farmington, d. 22 July 1689. Hannah was b. abt 1629, m. Nathaniel Prichard, 4 Feb 1652 in Springfield, d. 17 Sep 1690. Deliverance was b. 22 Sep 1627, d. 10 June 1718. Miss Langton (first name unknown) was b. abt. 1625. m. William Corbee abt. 1645 in Southampton, MA.No date of death given for her.I have seen a Bridget listed as George's dau. But that has not been confirmed.
In his will George identifed Hannah and Miss Langton by their husband's names. George's place of birth has not been confirmed, as yet.
