Hi Bebe and WELCOME to WikiTree!
You're doing the right thing by wanting to merge all the duplicates you have found. I'll try to guide you through the process.
First, when there are multiple duplicate profiles (more than just 2), it is important to have the final remaining profile be the one that has the correct LNAB (Last Name At Birth) and the lowest number. If Kitchell is the correct LNAB, then you want to start by identifying the profile with the LNAB Kitchell that is the lowest number of all the duplicates.
Then, one by one, propose either a merge or an unmerged match (I'll discuss that later) between each duplicate and the Kitchell you want as the final one. It is important not to merge A into B and then B into C - you want to merge A into C and B into C. It may sound strange (and I can explain it, but it's a long explanation) but this makes a difference in how fast WikiTree can display a profile page when you request it.
If you are sure that the profiles are duplicates, then you would propose a merge. If there are minor differences, such as maybe slight difference in birth date or 2 different places that are near each other, these need to be resolved before the merge is completed. For these cases, you want to create an unmerged match and then work with the other profile manager to agree on the correct data before you propose the merge.
If you scroll to the bottom of a profile, you'll see links to propose a merge, add an unmerged match, and also add a rejected match (don't worry about this one for now, though).
Click the link you want and put the WikiTree ID of the profile you want in the space provided. If the LNABs are different, make sure that you follow the instructions to have the CORRECT LNAB in the bottom space. You will be asked to enter the reason you think the profiles should be merged - here is where you indicate your basis for determining that they are duplicates or, in the case of an unmerged match, you can indicate what still needs resolution before they can be merged.
This is a complicated topic - if you have any questions about what I wrote here, please post again or send me a private message and I'l try to expand on the answers or do it for you on the first one or two so that you can see what I'm doing until you get the hang of it. I promise that it will soon become second nature to you, even though it might seem confusing at the start.
