Hello Barb. I think I have found what happened.
Since your CC7 is under 1000, you can see it all using the "My Connections" app. If you have installed the Wiki Browser Extension, you can explore each circle as a Table, that you can sort in different ways, including by last modification date.
I did it for your CC7, found four profiles in your C7 last edited on July 23, including Deborah Lindley. and her husband James Newlin. Looking at the changes history, I found out that both profiles have gone through a duplicate merge, and for James Newlin, it was on July 23.
So I suppose his duplicate profile was also in your C7 before. The merge results of course in one profile less, but it's rather good news in this case.
