Cousins - a lot of them

We have a lot of cousins. Both of us do. And we have multiple layers of cousins. The Man's are mostly around here. We see both sides all throughout the year. And there are multiple generations hanging out together now that the little ones are all growed up. And here is a good one for you - we also see my father-in-law's cousin's children a lot. Basically we just call them all cousins. So much easier that way. I tried figuring it out one day and got stumped. Then I found this little chart and it helped so much. (BTW - the above referenced is The Man's second cousin.)
