From Wikitree:
"Anderson indicates that the origin of Robert Andrews of Ipswich is unknown.[6] The supposed parents of Robert, Richard Andrews and Elizabeth Andrews, have been detached from this Robert, as their son, the captain of the Angel Gabriel must have been a different Robert Andrews.
...
While the Andrews Memorial (as cited in various sources, such as History of the Andrews Family...[7]%29 claims that Robert Andrews came over on the Angel Gabriel in 1635 (and that he was owner and master of that ship), according to Anderson's Great Migration,[8] Robert Andrews could not have been a passenger on the ill-fated Angel Gabriel in 1635:
“Andrews was admitted to Massachusetts Bay freemanship on 6 May 1635, an event which implies his arrival in New England by 1634 and which required his presence in New England on 6 May 1635. The Angel Gabriel was riding at anchor near Bristol, England, on 26 May 1635, and did not sail for New England until 4 June.”
Anderson suggests that Robert was born about 1593, and that he married Elizabeth ____ (probably a widow) by about 1618. He lists 4 children for Robert and Elizabeth Andrews, and estimates their birth years as follows: Alice, b. say 1618, Abigail, b. say 1623, John, b. about 1628, and Thomas, b. say 1630. Another daughter, Elizabeth, born by 1619, who married Humphrey Griffin of Ipswich, was likely Robert’s step-daughter, the daughter of his wife Elizabeth from a previous marriage. Anderson explains in some detail how he came to that conclusion."
In accordance with Anderson's research, I have detached Robert Andrews, of Ipswich as a child of Richard Andrew and Elizabeth Andrews
