if they are the Oren H. & Annie L. Hunt that I find living in Greenville in the 1910 census with daughter Mary L., age 1, then unfortunately they married before the time that South Carolina started recording marriage licenses (it began in 1911; they appear to have married around 1907). If you know what church they belonged to, you might be able to find record of their wedding there; other than that, your best bet is probably other family members - posting your query in a public forum like this one was a good move. We are in the process of indexing the marriage announcements that appeared in the Greenville News, but we're only up to 1902, so even if there was one, we won't have it indexed for quite a while.
If you have any other questions or need further assistance, don't hesitate to contact us in the South Carolina Room. Best of luck with your research!
