Edward Riggs was the immigrant to America landing in Boston early in the summer of 1633.He was born in England in about 1590. Most sources state that the family was from Lincolnshire,but I have been told that his marriage record is in Nazine, which is in Essex County, adjacent toLondon. In Boyd's Marriage Records, we find that Edward Riggs married Elizabeth Holmes inWalthan Abbey, Nazine Parish, Essex in 1618. He was accompanied to the new world by thisfirst wife Elizabeth Holmes and two sons and four daughters. They settled down to farming inthe town of Roxbury which is today a part of Boston. Roxbury was originally settled by familiesf
rom the area of Nazine in Essex County. This fact seems to lend credence to the idea that thiswas the area that Edward did come from and not from Lincolnshire much further up the English coast.

Born by about 1593, based on date of first marriage. Came from Nazeing, Essex to Massachusetts Bay in 1633 & settled in Roxbury MA. Died in Roxbury 5 March 1671/2.
Married: (1) Nazeing, Essex, 16 September 1618 Elizabeth Holmes; she was buried at Roxbury October 1635.
His wife was from Nazeing. They married there and all their children were born and baptized there.
I haven't found any proof that this Riggs line connects at all to the Riggs family of Lincolnshire.
