In 1780, being employed as agent to explore a tract of wild land, he purchased a lot of fifty acres in what is now the town of Hillsborough. In the spring of the succeeding year, he built himself a log hut, and began the clearing and cultivation of his tract. Another year beheld him married to his first wife, Elizabeth Andrews, who died within a twelvemonth after their union, leaving a daughter, the present widow of General John McNeil. In 1789, he married Anna Kendrick, with whom he lived about half a century, and who bore him eight children, of whom Franklin was the sixth. Although the Revolutionary soldier had thus betaken himself to the wilderness for a subsistence, his professional merits were not forgotten by those who had witnessed his military career. As early as 1786, he was appointed brigade major of the militia of Hillsborough County, then first organized and formed into a brigade. And it was a still stronger testimonial to his character as a soldier, that, nearly fifteen years afterwards, during the presidency of John Adams, he was offered a high command in the northern division of the army which was proposed to be levied in anticipation of a war with the French republic. Inflexibly democratic in his political faith, however, Major Pierce refused to be implicated in a policy which he could not approve. “No, gentlemen,” said he to the delegates who urged his acceptance of the commission, “poor as I am, and acceptable as would be the position under other circumstances, I would sooner go to yonder mountains, dig me a cave, and live on roast potatoes, than be instrumental in promoting the objects for which that army is to be raised!” This same fidelity to his principles marked every public, as well as private, action of his life. In his own neighborhood, among those who knew him best he early gained an influence that was never lost nor diminished, but continued to spread wider during the whole of his long life. In 1789, he was elected to the state legislature and retained that position for thirteen successive years, until chosen a member of the council. During the same period he was active in his military duties, as a field officer, and finally general, of the militia of the county; and Miller, McNeil, and others learned of him, in this capacity, the soldier-like discipline which was afterwards displayed on the battle-fields of the northern frontier.
