I just received civil war records that references these folks. According to the records on file Martha Hall was married to Horace N. Smith in Ohio in 1853. They had two children and were divorced in 1858 in Wabash Co. MN according to an affidavit. There is also a letter from the county clerk stating no record of a divorce. Records state that Martha Hall married George W. Waskey and died Dec 5, 1870 in Lake City MN (leaving a will).
Horace N. Smith married Margaret Cocagne in Mazeppa, Wabasha MN. in March 1865. They had 4 children. He died in 1909.
I am researching Horace Smith and his marriage to Martha Hall was a surprise. I would be interested in any info you have about where in OH they may have lived and any info on the two children born of Horace & Martha.
