He appears, however, to have held the rank of colonel, though his name does not occur in Peacock's Lists, and after the Restoration he made his services in the royalist cause a claim to the favour of Charles II.
On 20 March 1646–7 his wife petitioned that the estate might not be let to other tenants, as she was endeavouring to collect the fine; this also was granted, as was Walrond's request that his eldest son George might be included in the composition.

When Sir George Ayscue, the Commonwealth commander, arrived in October 1651 and created a revolution in the island, Walrond was one of those banished for a year by act of the assembly on 4 March 1651–2.
His son John, secretary to Willoughby, arrived with his father's commission on 17 December; Sir Thomas Modyford thereupon surrendered his post, and Charles II was proclaimed on the 20th.

On 19 October he issued a warrant for his imprisonment until he should account for sums he had received as president from the Spaniards in return for trading facilities; he also appropriated Walrond's house as his official residence.
Walrond's eldest son, George, lost an arm fighting for Charles I, succeeded to his father's Spanish titles, and died in Barbados in 1688, leaving issue; his descendants were long prominent in Antigua.
