Thomas Delano Sr was a son of a Huguenot emigrant (1540-1790).
The Great Migration project assigns Dr Thomas Delano a birth date of 1639  although the old Delano family history prefers 21 Mar 1642 in Duxbury, Plymouth, New England.
Dr. Thomas Delano was a polymath--in addition to being a physician, he was a tailor and surveyor, and even served as the town constable.
He married Rebecca Alden before 1667, but, according to town records, that did not suffice to escape a fine for "carnal copulation before marriage.". Eight children resulted of this marriage.
The Delano family history states that Dr Thomas died 13 April 1723 and was buried in the Myles Standish Burying Grounds.
Given the relatively small population of the New England colonies in the 17th century and the difficult circumstances of new arrivals, intermarriage among established families was frequent. Delano descendants sometimes find that they can trace their lines back to more than one of Dr Thomas's children.
This material was moved from the biography of his first wife, who was a daughter of John Alden. Some older sources give her first name as Mary. It has been shown conclusively that her first name was Rebecca.
11. Mary 2 [Corrected to Rebecca 2 Alden, daughter of (John1). Born in Duxbury, about 1643; married 1667, Thomas Delano, son of Philip Delano and Hester (Dewsbury) Delano. One authority says he was born March 21, 1642. Mary, his wife, died after her father's death, and before Oct. 24, 1699, when he married "widow Hannah Bartlett." I think she was the widow of William Bartlett, who left her with one child, Mary, who married John Turner. William Bartlett was the son of Benjamin and Ruth (Pabodie) Bartlett. Thomas Delano died April 15, 1723. He makes no mention of his second wife, so she was probably dead. This will is to be found in Plymouth Probate Records, Vol. 4, p. 388. In this will and elsewhere he is called Doctor. It is dated Oct. 5, 1722. Inventory taken by John Alden and Samuel Weston, April 29, and proved May 6, 1723. He gives "to eldest son Benoni, 5 shillings. To Thomas, jr., J of lot of land in Middleboro, to Jonathan a beech lot (swamp), to David 5 shillings, to daughter Mary best bed and furniture, to Sarah Drew 5 shillings, Ruth Drew next best bed. Granddaughter Deborah Weston executrix, and Joseph Delano, son, executor. Witnesses, Hannah Alden, Samuel Weston and Joshua Delano.
