Powell’s father, Morgan, lived at Greenhill, on the southern side of Milford Haven. One of the few merchants of substance at the end of Elizabeth’s reign to operate from the decayed town of Pembroke, where he leased the ferryhouse, Morgan was principally engaged in the local coastal trade, but he also imported and exported goods in partnership with his half-brother Thomas of Haverfordwest and was a member of the Bristol branch of the Elizabethan Spanish Company. Like his father before him he served as Pembroke’s mayor, in 1591 and 1602.
Powell himself was born in about 1576 and was named after his paternal grandfather. His father’s prosperity enabled him to attend university, Clifford’s Inn and the Middle Temple, but he was not a devoted scholar, being fined three times for absence from readings.
Powell’s father died in May 1622, but before that time the future MP evidently exercised some control over his father’s financial affairs. Powell’s appointment as mayor of Pembroke in 1619 points to this conclusion, as does an Exchequer suit which shows that Morgan had transferred his Crown lease of the Pembroke’s grist mills to his son by 1619.
Powell was elected to Parliament for the first time in December 1620, when he was returned for Pembroke Boroughs. In the previous Parliament the seat had been held by (Sir) Walter Devereux, lord of the manor of Lamphey, a property located a few miles south-west of Pembroke, but Devereux, who may have been serving in the Palatinate alongside his half-brother the earl of Essex, seems to have been unavailable for re-election. The obvious replacement for Devereux was not Powell but Devereux’s tenant, Richard Cuny, who had represented Pembroke Boroughs in the first Jacobean Parliament. However, as mayor of Pembroke (and thus the borough’s returning officer) Cuny was ineligible. Cuny nevertheless played a pivotal role in the election by using his position as mayor to marshal support for Powell, his brother-in-law, to whom he transferred his lease of Lamphey in October 1620.
Wogan was outraged at being denied a fair election and, together with the excluded out-boroughs, he petitioned the Commons for redress. As a result, Powell attended the committee for privileges at the beginning of April.
Even before Powell was granted permission to return home, he had long been absent from the House.
Powell served as mayor of Pembroke for a second time in 1622, during which time he was also prosecuted in Chancery by Sir Thomas Canon* of Haverfordwest, whom he described as ‘a very troublesome, litigious and contentious person’.
Powell left no trace on the records of the 1624 Parliament beyond that already mentioned, nor does he appear in accounts of the 1625 assembly, when he was again elected to serve for Pembroke Boroughs. Then, as in 1621, he owed his opportunity to represent Pembroke to the absence of Sir Walter Devereux, who was serving in his brother’s regiment in the United Provinces, and perhaps also to Richard Cuny, whose final term as mayor of Pembroke coincided with the parliamentary elections. It is not known whether Powell again attempted to step into Devereux’s parliamentary shoes at Pembroke Boroughs in 1626 and 1628, when Devereux was returned for Tamworth, but if he did he was forced out of the running by Hugh Owen of Orielton who, years later, served as executor to Powell’s erstwhile opponent Sir Thomas Canon.
Powell and his brother-in-law John Meyrick bought the wardship of Nicholas Adams’ son in 1629 for £133. 6s. 8d.
Powell’s financial problems undoubtedly stemmed from the size of his family - he had about eight surviving children - and the smaller than expected profits arising from his coal mines. In his will of 7 Mar. 1636, he ordered his lease of Lamphey manor to be sold ‘with all convenient speed’ so as to raise £2,000 for his daughter Lucy, his only child by his second marriage. In order to provide an income for his younger children he also instructed that the profits from his coal mines be set aside for 21 years after his decease. However, this decision led him into a serious disagreement with his eldest surviving son, Thomas, who naturally stood to lose by this arrangement. Relations between Powell and Thomas were so strained that the latter was warned that if he failed to hand over the remaining part of his wife’s dowry, amounting to £300, plus bonds for an additional £400, he would be denied possession of Greenhill, which had been assigned to his wife as her jointure.
The precise date of Powell’s death has not been established, although his will was proved on 5 May 1636, nor is it known where he was buried. One of his surviving younger sons, Rice Powell, achieved prominence as a colonel in the parliamentary army during the First Civil War and as a leading royalist during the second.
