In the 1860 Ohio, Mahoning, Milton Twp Census and Civil War enlistment papers, Harvey said he was born ca. 1832 in Mahoning (then Trumbull) county Ohio.He married Samantha Leonard (dau of Nicholas and Isabella) 30 DEC 1853. Children were: Isabella J. b. ca 1857; john William b. 2 SEP 1858 (my grgrgrandfather)and Mary b. ca Oct 1861. Harvey enlisted in the 19th Ohio Vol. Inf, Co. D, 1 OCT 1861, and was divorced from Samantha Feb 1862. He was given a discharge in Feb 1863 to join the 1st Miss. Marine Brigade (River Ram Fleet) in St. Louis, MO.He was discharged as a SGT on 31 AUG 1864 at Vicksburg, Miss.There is no trace of him after that.Samantha and the children were in the 1870 census in Milton twp as Leonards, and in Newton Twp, Trumbull in the 1880 Census.Dau. Isabell married a Ewing , but still living with Samantha and had a 2 mo old dau.Mary marr. a John L. Force on 4 JUN 1880. Her name was recorded as McColumn.I have searched surrounding county census for 1850 and can find no child named Harvey in a McCollum family. I can't find any record of him prior to his marriage in 1853 or after his discharge in 1864.I would really appreciate hearing from anyone that has info on Harvey.This is not the son of John from Austintown that some said was in the 19th Ohio. That info is incorrect.
