SLACK, LEIGHTON P., son of Joel B. and Mary (FULLAM) SLACK, was born in Woodstock, Vermont, June 18, 1867. He is a descendant from William SLACK, who came to Massachusetts from Yorkshire, England, in the latter part of the seventeenth century. Through his father's mother, Prudence BARTLETT, he traces. his ancestry to Josiah BARTLETT of Declaration of Independence fame. His maternal ancestry is directly traceable to Hon. Francis FULLAM, who moved to Watertown, Massachusetts, in 1683 from Fullam Place, near London, England, and was for many years a judge of the superior colonial court of Massachusetts and for seventeen years a member of the colonial legislature of the same colony. 

      He received his early education in the common schools of his native town and at Black River academy at Ludlow, Vermont; studied law with Hon. S. C. SHURTLEFF and Judge M. E. SMILIE, at Montpelier; was admitted to the bar of this state at the October term, 1892, and two years later to the district and circuit courts of the United States. During his years in the academy and while pursuing his legal studies, he taught school successfully in various towns in Windham and Washington counties. Soon after his admission to the bar he located in Barre, where he formed a partnership with Frank J. MARTIN, Esq., of that city. This arrangement continued until May, 1895, when he moved to St. Johnsbury and formed the partnership with Hon. Alexander DUNNETT, which still exists. The firm of DUNNETT & SLACK is one of the leading law firms of the state, and enjoys an extensive practice in both the state and federal courts. 

      Mr. SLACK is a careful, studious, and painstaking lawyer; thorough in the investigation and preparation of his cases, and frank and candid with his clients and with the court. During his term as state's attorney of Caledonia county, -- from 1898 to 1900, -- he won the confidence and admiration of all law abiding people by his thorough and fearless enforcement of the law. During this term he prepared the first indictment, under our so-called Bucket-Shop law, ever sustained by the supreme court of the state. The appreciation of his services was shown by the almost universal demand for his reelection. This he, however, declined, in order that he might devote his entire time to the general practice of his chosen profession. 

      He married in August, 1894, Estelle H., daughter of W. H. H. and Emily MEARS of Marshfield, Vermont. She died in April, 1896. He contracted a second alliance July 11th, 1899, with Leah E. MEARS, a sister of his former wife. They have one child, Ruth Estelle. In his religious views he is a Congregationalist, and is a member of the North Congregational church of St. Johnsbury. He is a past chancellor of Apollo lodge, Knights of Pythias, a member of the Grand lodge of Vermont, and of the Grand Tribune of the latter body. He is also a member of Passumpsic lodge, No. 27, F. & A. M.; Haswell chapter, No. 11, of Royal Arch Masons; Palestine Commandery and the Mystic Shrine. He is at present high priest of Haswell chapter.
