Richard Warren married Elizabeth Walker, at Great Amwell, Hertfordshire, on 14 April 1610. Elizabeth Walker was the daughter of Augustine Walker of Great Amwell. She was baptised at Baldock in September 1583. This information came to light with the discovery of Augustine Walker's will dated 19 April 1613, in which he named his daughter Elizabeth and her children Mary, Ann and Sarah Warren.
Based on his marriage in Hertfordshire, speculation is that he also came from that county. His parentage and apparent birthplace are uncertain, but there is a Warren family that may be of that ancestry residing in the vicinity of Therfield.
The author and genealogist Charles Edward Banks states that Warren came from London and was called a "merchant" of that city. Warren was one of those very few English merchants who signed on to make the Mayflower voyage as a member of the Leiden contingent. His reason for this has not been determined, and given his status, it is unusual that little is actually known of him.
At the time of the Mayflower's voyage in 1620, Richard and his wife had five daughters: Mary, Ann, Sarah, Elizabeth and Abigail. But Richard came on the Mayflower alone, deciding to wait until conditions in the New World were satisfactory before bringing over his family. Governor William Bradford recalled of that time, "Mr. Richard Warren, but his wife and children were lefte behind, and came afterwards."
The Mayflower departed Plymouth, England on 6/16 September 1620. The small, 100 ft (30 m) ship had 102 passengers and a crew of about 30–40 in extremely cramped conditions. By the second month out, the ship was being buffeted by strong westerly gales, causing the ship's timbers to be badly shaken with caulking failing to keep out sea water, and with passengers, even in their berths, lying wet and ill. This, combined with a lack of proper rations and unsanitary conditions for several months, attributed to what would be fatal for many, especially the majority of women and children. On the way there were two deaths, a crew member and a passenger, but the worst was yet to come after arriving at their destination when, in the space of several months, almost half the passengers perished in the cold, harsh, unfamiliar New England winter.
On 9/19 November 1620, after about three months at sea, they spotted land, which was the Cape Cod Hook, now called Provincetown Harbor. After several days of trying to sail south to their planned destination of the Colony of Virginia, strong winter seas forced them to return to the harbor at Cape Cod hook, where they anchored on 11/21 November. The Mayflower Compact was signed that day. Richard Warren's name appears 12th in the list, according to Nathaniel Morton's enumeration of it.
In the New World
Warren participated in some of the early explorations of Cape Cod, when a suitable settlement location was being searched for.
One such extensive exploration began on Wednesday, 6 December 1620 in freezing weather using the ship's shallop, a light, shallow-water boat with oars and sails which was navigated by two pilots, with a master gunner and three sailors. Pilgrims on board, in addition to Warren, were senior members Governor John Carver, Bradford, Myles Standish and Edward Winslow along with John and Edward Tilley, John Howland, Stephen Hopkins and Hopkins' servant, Edward Doty. These persons were less than half the number of the previous exploration due to many having been felled by illness. The English explored in freezing temperatures wearing unsuitable clothing due to not planning for the severity of the New England winter weather. This exploration would result in their first encounter with Indians and did not turn out well, as they learned that slow-firing muskets were no match for rapid-fire arrows. This Indian challenge to the Pilgrims was later known as the "First Encounter".
In the 1623 Division of Land, Warren received two "akers" (acres) of land in one area—"these lye one the north side of the towne nexte adjoyning to their gardens which came in Fortune" and five acres in another—"these following lye on the other side of the towne towards the eele-riuer (Eel River)" (as Richard "Waren").
In Plymouth two more children were added to their family. In 1624 his wife Elizabeth gave birth to a son Nathaniel and in 1626 another son, Joseph."
In 1626, 27 Plymouth settlers, called Purchasers, were involved with the colony joint-stock company which afterwards was turned over to the control of senior colony members. That group was called Undertakers, and were made up of such as Bradford, Standish and Allerton initially who were later joined by Winslow, Brewster, Howland, Alden, Prence and others from London, former Merchant Adventurers. The agreement was dated 26 October 1626 and was finalised sometime in 1627. Warren may have originally been a party to the agreement, but due to his death, which may have been sometime in 1628, his name on the charter was replaced by that of his wife, recorded as "Elizabeth Warren, widow." Elizabeth Warren, as a widow, was named in a law passed by the Plymouth Court specifically to give her the Purchaser status that her husband had: "hee dying before he had performed the bargaine, the said Elizabeth performed the same after his decease, …"
In the 1627 Division of Cattle, Richard, his wife and their seven children, in the ninth lot, received several animals that had arrived on the ship Jacob, apparently in 1625. The ninth lot also listed John Billington and the Soule (spelled Sowle) family.
In his "Increasings and Decreasings", Bradford assigns Warren the title of "Mr." which indicates someone of status, but does not mention him at all in his recording of Plymouth history. And except for a few mentions elsewhere, not very much is known about him in Plymouth, but the Warren family does seem to have been among those with wealth.
During her widowhood, Elizabeth Warren's name is noted in Plymouth Colony records. She was listed as the executor of her husband's estate, paying taxes as head of household and as an independent agent in her own right.[dead link]

Death and burial
Warren died of unknown causes, possibly sometime in 1628, exact date unknown. Morton, in his 1669 book New England's Memorial, recorded that "This Year  died Mr. Richard Warren, who …. was an useful Instrument; and during his life bare a deep share of the Difficulties and Troubles of the first Settlement of the Plantation of New-Plymouth [sic]" (p. 68).
From Bradford's recorded Plymouth history:
"Mr. Richard Warren lived some *4* or *5* years, and had his wife come over to him, by whom he had *2* sons before [he] dyed; and one of them is maryed, and hath *2* children. So his increase is *4* But he had *5* doughters more came over with his wife, who are all married, and living, and have many children."
Warren's widow Elizabeth lived to be more than ninety years old, dying on 2 October 1673. Her death was noted in Plymouth Colony records: "Misstris Elizabeth Warren, an aged widow, …haveing lived a godly life, came to her grave as a shoke of corn fully ripe". She was buried at Burial Hill in Plymouth.
Because all seven of Richard and Elizabeth Warren's children survived and had families, they have very many descendants today. Some notable descendants include:
