Adam de Feypo is first mentioned in The Red Book of the Echequer 1166, p283 (England) as being one of the knights of Hugh de Lacy in Herefordshire, England. He was possibly a castellan of one of the de Lacy castles on the Welsh border. As the holdings of de Feypo in Herefordshire appear to have been modest it is no surprise that he reappears in Ireland in 1171 where there are great 'possibilities'.
Why were the Early Normans drawn to Ireland? They were like all settlers interested in making a better life for themselves and enhancing their wealth. Ireland was the 'Wild West' of their day and Giraldus Cambrensis painted an attractive picture of this island.
'This is the most temperate of all countries. Cancer does not here drive you to take shade from the burning heat: nor does the cold of Capricorn send you rushing to the fire. You will seldom see snow here, and then it lasts only a short time. But cold weather does come with the winds here, not only from the west-north-west and north but equally from the east, the Favonius and the Zephyr. Nevertheless, they are all moderate winds and none of them is too strong. The grass is green in the fields in winter just as in summer. Consequently the meadows are not cut for fodder, nor do they build stalls for their beasts. The country enjoys the freshness and mildness of spring almost all year round. The air is so healthy that there is no disease-bearing cloud, or pestilential vapour, or corrupting breeze. The island has little use for doctors. You will not find many sick men here, except those that are actually on the point of death. There is scarcely any mean between constant health and final death. Anyone born here, who has never left its healthy soil and air, if he be the native people never suffers from the three kinds of fevers. They suffer only from ague (a cold!) and even that is only seldom'
The inducements for Adam de Feypo to come to Ireland were possibly twofold. Firstly it would have been his duty to his overlord, de Lacy. Secondly the colonisation opportunities were enormous which included the prospect of much land. He eventually ended up with over 40,000 acres. Not only was there status but adventure as well as the profits from corn, animals and timber and the abundance of cheap labour.
When Hugh de Lacy was involved in the Conquest of Ireland in 1171 with Strongbow, Adam de Feypo was one of the knights he placed in charge of a number of his troops and who fought alongside him. On the successful outcome, for King Henry's occupying army. Hugh de Lacy had the Kingdom of Meath and Dublin bestowed on him. Hugh then established a defensive shield around Dublin by granting land to a number of his loyal knights. As part of this cordon Adam de Feypo was granted Santry, by the spring of 1173, before de Lacy had to go off to Normandy in the service of King Henry.
