Boyle's marriage to heiress Joan Apsley in 1595 brought him considerable wealth and allowed him to purchase Raleigh's estates for £1,500. He brought over settlers from England and in 1616 became Lord Boyle in recognition of the introduction into the maritime ports of our Province of Munster, and particularly in the neighbourhood of Youghal ... a very excellent Colony, consisting of veteran soldiers and many other persons, brought by himself out of England. 

(Townshend) Boyle was influential in the granting of a new charter to Youghal in 1609 which was important in the future development of the town. Exports from the area included pipe staves, wool and cattle, while goods such as wine, cloth, tobacco and luxury items for the English settlers were imported. Richard Boyle played an important role in defending Youghal during the risings of 1641 and ensured that it remained loyal to the English cause. He died in 1643 and was buried in St. Mary's Collegiate Church in Youghal.
