George was the son of George and Barbara Haley, Rachel's parentage is unknown at this point. George was born in Switzerland and came with his parents to Fairfield County, Ohio in 1816. Rachel was born in Fairfield County in 1816. George was a minister in the Evangelical Association, and one of his early appointments may have been in Hardin County.
I do hereby certify that on the first day of January AD 1835 by virtue of a license from the Clerk of the Court of Common Pleas George Haley and Rachel H Gary were legally joined in marriage by me a Justice of the peace in and for the county of Hardin. Given under my hand and seal this fifteenth day of January A.D. 1835 - George H. Hauser, J.P.
Interesting to note that Rachel's middle initial "H." was given, perhaps to distinguish her from another Rachel Gary in the area.
