I followed a link to the Illinois State Archives and ended up at a higher level that showed more collections. I went to the marriage section and very quickly found the dates for eleven McClurken or McClurkin marriages in my Family Tree Maker file. This also identified two spouses and the last name of a third. These archives did not include all the McClurken marriages. A few, that are on file in Washington County, were not in these archives. However, I will be revisiting the Illinois State Archives to see what other information I can locate.
