The origins of the barony of Sandys are unclear, hence the rules governing its descent are equally uncertain. Burke claimed that it was from his father that Sandys inherited the title, but it has been demonstrated convincingly elsewhere that Elizabeth, Baroness Sandys, outlived her son, a royalist colonel who died of his wounds after a skirmish at Cheriton in 1644. It was on her death, assuming she enjoyed the barony as suo jure 5th Baroness Sandys, that the peerage passed to her grandson.
A remote descendant of the Plantagenet kings, Sandys could claim kinship with a number of prominent families, including the Manners earls (later dukes) of Rutland, and the Wriothesley earls of Southampton. Balliol College, Oxford also proved an important point of contact. Both Sandys and his younger brothers Henry Sandys, later 7th Baron Sandys, and Edwin Sandys, later 8th Baron Sandys, attended the college, as did their cousin, Richard Atkyns. Sandys was accompanied to France in 1642 by another Balliol associate, his future brother-in-law Henry Savage, later master of the college and rector of the family advowson of Sherborne St John.
Sandys’ estates were largely centred on Mottisfont Abbey in Hampshire, the Sandys’ former seat of The Vyne (Sherborne St John), which had been in the family since the fourteenth century, and which had been their principal residence since the sixteenth century, having been sold to Chaloner Chute‡ in 1653, shortly after Sandys’ marriage to Lady Mary Cecil.
Despite his father’s death in the Civil War, and some suggestion that he too participated on the royalist side, Sandys escaped confiscation of his estates. He appears to have enjoyed sufficiently amicable relations with Richard Cromwell‡ to take part in a hunting party with him and other Hampshire royalists, Charles West, 5th Baron De la Warr, and Sir William Kingsmill, in February 1655.
With the restoration of the House of Lords uncertainty over the descent of his peerage gave rise to doubts about Sandys’ right to sit. His case was referred to the newly appointed committee for privileges, which quickly decided in his favour, thus accepting the claim that his grandmother was indeed suo jure Baroness Sandys. Such a claim would be unlikely to succeed under modern peerage doctrine, and it is arguable that his writ of summons effectively created an entirely new barony.
Sandys does not appear to have been active in the elections for Hampshire of March 1661. He took his seat at the opening of the new Parliament on 8 May and on 11 May was named to the sessional committees for privileges, petitions and the Journal. Absent at a call of the House on 20 May, Sandys returned two days later and was thereafter present for just under half of all sitting days, during which he was named to a further seven committees. Sandys was missing from the attendance list at the opening of the second session on 18 Feb. 1663 but was, nevertheless, nominated to the sessional committees for privileges and the Journal, suggesting that he took his seat at some point during the day. On 25 Feb. he was named to the committee for petitions and over the course of the session he was nominated to a further five committees, including that for the bill for making rivers in Surrey, Sussex and Hampshire navigable, in which he may have had some local interest. Although Sandys was present in the House on 10 July, Wharton assessed him as doubtful over the question of the attempted impeachment of Edward Hyde, earl of Clarendon, by George Digby, 2nd earl of Bristol. His attendance improved in the ensuing session of 1664, when he was present on approximately 61 per cent of all sitting days, but he was absent for the entirety of the 1664-5 session and he attended a mere three days of the fifth session of October 1665, during which he was named to just one committee.
Sandys attended approximately a third of all sitting days during the 1666-7 session but he was again named to just one committee. Between July and October 1667 he appears to have been involved in some sort of dispute with Lady Gardiner involving leases in London perhaps connected with the aftermath of the Great Fire.
Sandys sat for the last time on 9 May 1668; by 14 Sept. he was dead.
