After Greatraks settled down in his civil capacity, he seems to have been a blameless member of society; but his religious convictions were extremely rabid, and strong on the Protestant side. Writing in 1668, he says: ‘About four years since I had an Impulse, or a strange perswasion, in my own mind (of which I am not able to give any rational account to another) which did very frequently suggest to me that there was bestowed on me the gift of curing the King’s Evil: which, for the extraordinariness of it, I thought fit to conceal for some time, but at length I communicated this to my Wife, and told her, That I did verily believe that God had given me the blessing of curing the King’s Evil; for, whether I were in private or publick, sleeping or waking, still I had the same Impulse; but her reply was to me, That she conceived this was a strange imagination: but, to prove the contrary, a few daies after there was one _William Maher_ of _Salterbridge_, in the Parish of _Lissmore_, that brought his Son _William Maher_ to my house, desiring my Wife to cure him, who was a person ready to afford her Charity to her Neighbours, according to her small skill in Chirurgery; on which my Wife told me there was one that had the King’s Evil very grievously in the Eyes, Cheek, and Throat; whereupon I told her that she should now see whether this were a bare fancy, or imagination, as she thought it, or the Dictates of God’s Spirit on my heart; and thereupon I laid my hands on the places affected, and prayed to God for Jesus’ sake to heal him, and then I bid the Parent two or three days afterwards to bring the Child to me again, which accordingly he did, and then I saw the Eye was almost quite whole, and the Node, which was almost as big as a Pullet’s Egg, was suppurated, and the throat strangely amended, and, to be brief (to God’s glory I speak it), within a month discharged itself quite, and was perfectly healed, and so continues, God be praised.’ This may be taken as a sample of his cures, albeit his first; and, although he excited the enmity of the licensed medical profession, he seems to have cured the Countess of Conway of an inveterate head-ache, which greatly enhanced his reputation. He died no one knows when, but some time early in the century.
