Mr. John M'Clelland having gone through several branches of useful learning, kept a school for some time at Newton in Ireland, where he became instrumental in training up several hopeful young men for the university. Afterwards he was tried and approven of by the honest ministers in the county of Down, and being licensed, he preached in their churches, until (among others) for faithfulness, he was deposed and excommunicated by the bishops. He was also engaged with the rest of his faithful brethren in their intended voyage to New England in the year 1636, but that enterprise proving abortive (by reason of a storm which forced them to return back to Ireland), he preached for some time through the counties of Down, Tyron and Dunnegal in private meetings, till being pursued by the bishop's official, he was obliged to come over in disguise to Scotland, where about the year 1638, he was admitted minister at Kirkcudbright, in which place he continued until the day of his death. It would appear that he was married to one of Mr. Livingston's wife's sisters, and the strictest friendship subsisted betwixt these two worthy men, both while in Ireland, and after their return to Scotland. While he was minister at Kirkcudbright, he discovered more than ordinary diligence, not only in testifying against the corruptions of the time, but also for his own singular walk and conversation, being one who was set for the advancement of all the practical parts of religion, and that as well in private duties as in public.----For instance, When Mr. Henry Guthrie then minister at Stirling (but afterwards bishop of Dunkeld), thought to have brought in a complaint to the general assembly 1639, against private society meetings (which were then become numerous through the land), yet some of the leading members, knowing that Mr. Guthrie did it partly out of resentment against the laird of Leckie (who was a great practiser and defender of these meetings), thought proper, rather than it should come to the assembly, to yield that Mr. Guthrie should preach up the duty of religious exercise in families, and that Messrs. M'Clelland, Blair and Livingston should preach against night-meetings (for they were so called then because mostly kept in the night) and other abuses, but these brethren endeavoured by conference to gain such as had offended by excess in this matter, but by no means could be prevailed with to preach against them, which so offended Mr. Guthrie, that he gave in a charge or complaint to the general assembly 1640, wherein he alledged these three ministers were the only encouragers of these meetings, Mr. M'Clelland roundly took him up, and craved that a committee might be appointed to try these disorders, and to censure the offenders, whether those complained of or the complainers, which so nettled Mr. Guthrie, the earl of Seaforth and others of their fraternity, that nothing was heard in the assembly for sometime for confusion and noise stirred up by them.
