Margaret Curtis was born in Braintree, Massachusetts, on February 22, 1685/6. She was the daughter of Theophilus Curtis and his wife Hannah Paine Curtis.
Margaret married her first husband, Benjamin Thayer, in Braintree on August 17, 1704. They were the parents of three children, all born in Braintree:
Margaret, born 26 1705, married on 9 May 1728 to Amos Stetson. She was living Mar. 31, 1785.
Benjamin, born 23 February 1707/8
Zebulon, born 29 August 1711, baptized Sep. 3, 1710 (according to Dorchester Church Record)
Benjamin Thayer died on 4 May 1712. His widow, Margaret Thayer, administered the estate.
Margaret married her second husband, John Hayden, in Braintree on 26 February 1713. After marriage she removed to the South Precinct of Braintree, which later became the town of Randolph. One child is recorded from this marriage:
John, baptized August 26, 1716 at Middle Parish in Braintree.
Margaret's date of death is not known. She was still living as of 1753.
It may be possible to confirm family relationships with Margaret by comparing test results with other carriers of her mitochondrial DNA.
Mitochondrial DNA test-takers in the direct maternal line:
Curtis-4668 and Curtis-2551 appear to represent the same person because: Same parents, same death date. The birthdates are 16 years apart, but I think the 1686 date is valid and the 1702 date is an error.
I've not been able to find any records for a Margaret Curtis born to these parents (nor any other parents) in or near Braintree in 1702. Also, the woman born in 1686 is recorded as marrying, having children, etc., so it's unlikely that the Theophilus and Hannah would have named a second daughter Margaret in 1702.
