John  is listed in the Royalist Composition Papers, which includes our John Botwright referenced twice; the first he gives his deposition that John Glasscock died in Nov 1646. And more importantly, the second reference includes John's signature - with the similar flourishes at the end of the signature as compared to John's signature above.

Few classes of records are better known to the genealogist than those which are styled the Royalist Composition Papers. This is doubtless due in no small measure to the fact that they relate almost wholly to those who suffered severely for their loyalty to King Charles the First. That they are readily consulted, by means of good indexes, has also increased their popularity with those who have access to the Public Record Office. The Royalist Composition Papers are the Records of the Committee for compounding with Delinquents, as those who took the part of the King in the great rebellion, or who professed the Roman Catholic religion, were styled by the Parliamentary party. This committee continued to exist from 1644 to 1657, during which time, to quote Mrs. Everett Green, they obtained "from the delinquents themselves":
1. A confession of their delinquency.
2. A pledge of adherence to the present Government.
3. A full account on oath of their possessions, real and personal.
Whereupon a legal report was made, and they were admitted to compound in proportions, according to their guilt; half the estate was exacted from any delinquent Member of Parliament;
one-sixth from those who had taken part either in the former or later war ; two-sixths or one-third from those who had been active in both wars, etc. Those who were in cities that surrendered on articles of war compounded according to the tenor of those articles.
The fines that were thus imposed by the committee, it is said, amounted to upwards of L1,304,957 pounds. But it is to be noted that this amount, large as it was, did not represent the loss sustained by the King's supporters. Many were not allowed to even compound, and their estates were wholly forfeited, as was the case also with those who had fled the country.
The Royalist Composition Papers are of the greatest interest and value in elucidating the family history, and ascertaining the actual landed and personal property of individuals during the period of the Commonwealth. The original papers are now arranged and bound up in two series, and are referred to by manuscript Indexes. The First Series consists of 7,300 sets of papers, bound in 113 folio volumes. It comprises the correspondence and orders of the Commissioners for sequestration and sale of the estates of the royalist nobility and gentry. The first portion of this series is arranged alphabetically, under the names of the Compounders ; then come the miscellaneous Petitions and Orders; and these again are followed by the Letters and Reports in a County arrangement.
The Second Series, of 3,634 sets of papers, bound in 54 folio volumes, is especially valuable. In these will be found the original particulars given in on oath of the estates and personal property of those royalists who were permitted to compound on payment of a fine, and the amount of the Compositions so levied on them by the Commissioners. 
 
John Botwright, Jr., son of John Botwright, Sr., traveled to Virginia around 1654 as an indentured servant. Two years later he imported eight individuals including two uncles (Thomas and William Cropley - younger brothers of John Botwright, Sr.'s wife, Elizabeth Cropley) and his father, John Botwright, Sr.
"Cert. is granted to Mr. John Botwright for four hundred acres of land for ye importeen of William Powell, Thomas Cropley, William Cropley, John Botwright, Henry Farloe, James Cassett, Elizabeth Bridge and Anne Scarlett."
 This key record, discovered by Dr. Ron Boatright, records John Botwright Jr. receiving a land certificate for 400 acres for importing eight individuals including his father (John Botwright Sr.) and two uncles (Thomas and William Cropley). There is no subsequent record of a land patent for the 400 acres by John Boatwright, so it is assumed that John sold or traded the land certificate rather than claiming the 400 acres of land. Although another posibility is that John claimed 400 acres in New Kent/Hanover county and those records were destroyed by fire.
