Marshall Bolds Champlain (December 22, 1824 in Stafford, Genesee County, New York – March 7, 1879 in Cuba, Allegany County, New York) was an American lawyer and politician.

Personal life[edit]

Marshall B. Champlain was born in 1824 to Dr. Gilbert B. Champlain.[1] He died of pneumonia in 1879.

Legal career[edit]

He was admitted to the bar in 1843, and practised at Cuba, N.Y. He was District Attorney of Allegany County in 1845.

He was a member of the New York State Assembly (Allegany Co., 2nd D.) in 1853; and was one of the Managers who prosecuted the impeachment of Canal Commissioner John C. Mather. He also successfully prosecuted Edward H. Rulloff for murder.[2] Another of his cases was against the Erie Railway Company.[3]

Political career[edit]

He was delegate to the 1860 Democratic National Convention at Charleston, South Carolina, and to the 1864 Democratic National Convention at Chicago.

In 1861 and 1863 he was the Democratic candidate for New York State Attorney General, but was defeated by his former fellow Democrats Daniel S. Dickinson and John Cochrane who were nominated by Union conventions of Republicans and War Democrats. In 1867, he finally was elected, and re-elected in 1869, to the office. In 1871 he was defeated when running for re-election.

He was a delegate to the New York State Constitutional Convention of 1867.
