The grandfather of Colonel Aaron Burr, the subject of these memoirs, was a German by birth, and of noble parentage. Shortly after his arrival in North America, he settled in Fairfield, Connecticut, where he purchased a large tract of land, and reared a numerous family. A part of this landed estate remained in the possession of his lineal descendants until long after the revolutionary war. During Colonel Burr's travels in Germany, in the year 1809, various communications were made to him, orally and in writing, by different branches of the Burr family, some of whom were then filling high and distinguished scientific and literary stations. His father, the Rev. Aaron Burr, was born in Fairfield, on the 4th day of January, 1715, and was educated at Yale College. In a manuscript journal which he kept, and which has been preserved, he says, "In September, 1736, with many fears and doubts about my qualifications (being under clouds with respect to my spiritual state), I offered myself to trials, and was approved as a candidate for the ministry. My first sermon was preached at Greenfield, and immediately after I came into the Jerseys. I can hardly give any account why I came here. After I had preached for some time at Hanover, I had a call by the people of Newark; but there was scarce any probability that I should suit their circumstances, being young in standing and trials. I accepted of their invitation, with a reserve, that I did not come with any views of settling. My labours were universally acceptable among them, and they manifested such great regard and love for me, that I consented to accept of the charge of their souls.
