This is what I think it is.
Brothers Thomas Preston, of Calvert County & Richard Preston, of Patuxent in Maryland parents unidentified, but probably originating in Yorkshire, emigrated to Virginia, and then to the Maryland Colony.
I think this is the reference you had found?
From the Tri County Researcher, FIRST IN FREEDOM By James R. Ewing. " INSTALLMENT 2, Charles Anderson, Signer of The Bush Declaration, 22 March 1775 ...
Thomas Preston was born in England in 1615. In 1635 or 1637 he and his brother, Richard, immigrated to Virginia and settled there. Later they objected to the actions, which they considered to be persecution, of the Governor of Virginia and, separately, moved up the Chesapeake to Maryland.
On 16 May 1665, Thomas Preston bought 500 acres of land lying on "The Clifts" of Calvert County which is a short distance north of the mouth of the Patuxent River and about 35 miles south of Annapolis. While in Virginia he married Elizabeth (family name unknown) and they had three children. The eldest, born about 1641, was Thomas Preston, Jr. The others were Elizabeth and Sarah and we have no knowledge of who they married.
The son grew to adulthood at The Clifts and married Mary Hewes about 1671. The second of their four children was James Preston, born 1675. ...
So this is a different line from Thomas Preston, of Kettringham in Norfolk who married Deborah Lady Preston They had a number of children baptized in Kettringham in the 1640s, but there's no note I've seen so far that this couple left children.
However, I believe their daughter Dorothy Stevens and her brother Christopher Preston did come to America.
Hope this works for you. I've seen you manager requests.
