The Rev. Mr. Mack was the son of Daniel Miner Mack and Rebecca Cordelia (Ayers) Mack. In 1840 he enrolled as a boarding student at the Newbury VT Seminary. In 1847 he was a student at the General Biblical Institute, Concord NH. In 1851 at age 26, he married Anna Roby, age 27. In 1860 they were in Royalton VT where he was pastoring the Methodist Episcopal Church there. In January 1862 he was commissioned a Union Army chaplain where he soon joined the 3rd VT Regiment. He resigned 27 Jul 1864 and returned to VT but was recommissioned 30 March 1865 and was present at Appomattox when General Robert E. Lee surrendered. His unit mustered out 11 Jun 1865 and Chaplain Mack decided not to return to a pastorate but to gain financial and prayer support for an orphanage. With the help of wealthy donors the Daniel Webster homestead in Franklin NH was purchased and the New Hampshire Orphans Home was founded. Daniel and Anna were involved there the rest of their lives.
