Richard Warren is a name that students do not study but is well-known in genealogical circles. This is because his family has a claim to the largest number of Mayflower descendants. He has more than John Howland, who also has quite a few.
Warren was a Stranger and investor when he migrated from Holland to the New World. This suggests that he had some money to invest and would have been an influential figure when the Mayflower set sail.
When he arrived with the Pilgrims at Cape Cod, he would become one of the signers of the Mayflower Compact. The document was written to give the colonists an independent form of government since they would not be settling in the Virginia colony.
His wife and five daughters would arrive aboard the Anne in 1623. He and his wife would have two sons in Plymouth.
He seems to have been one of the five assistant governors from 1624-1628.
In 1626, twenty-seven Plymouth settlers, called Purchasers, were involved with the colony joint-stock company, which afterward was turned over to the control of senior colony members.
That group was called Undertakers and was made up of such as William Bradford, Myles Standish, and Isaac Allerton initially, who were later joined by Edward Winslow, William Brewster, John Howland, John Alden, Thomas Pence, and others from London, a former Merchant Adventurers. The agreement was dated October 26, 1626, and was finalized sometime in 1627.
Richard 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 changed to that of his wife.
Richard Warren died at Plymouth in 1628, leaving his wife and seven children. This was written by a colonist who knew Warren:
This year  died Mr. Richard Warren, who hath been mentioned before in this book, and was an useful instrument; and during his life bore a deep share in the difficulties and troubles of the first settlement of the plantation of New Plimouth.
Richard Warren would become the ancestor of millions who trace their lineage back to the Mayflower. He and his wife would have 7 children, each having a large family that would number their descendants into the millions.
Despite the many descendants he would produce, there is little known of Richard's parents. There are some theories that give the name "William Warren" or "Richarde Waren," but nothing can be proven.
He married Elizabeth Walker, who outlived him by 45 years. She lived until the age of 90, seeing all of her children grow up, and would be a grandmother to many. She outlived two of her children as well.
